/**
* The class Servo uses the PWM class to implement its functions
*
* All PWMs use the same repetition rate - 20mS because that's the normal servo rate
*/
/**
* This is a hybrid system.
*
* The PWM1 module is used to directly control the Servo 0, 1 & 3 pins. This keeps
* the pulse width jitter to under a microsecond.
*
* For all other pins the PWM1 module is used to generate interrupts. The ISR
* routine does the actual setting/clearing of pins. The upside is that any pin can
* have a PWM channel assigned to it. The downside is that there is more pulse width
* jitter. The jitter depends on what else is happening in the system and what ISRs
* prempt the PWM ISR. Writing to the SD card can add 20 microseconds to the pulse
* width.
*/
/**
* The data structures are setup to minimize the computation done by the ISR which
* minimizes ISR execution time. Execution times are 2.2 - 3.7 microseconds.
*
* Two tables are used. active_table is used by the ISR. Changes to the table are
* are done by copying the active_table into the work_table, updating the work_table
* and then swapping the two tables. Swapping is done by manipulating pointers.
*
* Immediately after the swap the ISR uses the work_table until the start of the
* next 20mS cycle. During this transition the "work_table" is actually the table
* that was being used before the swap. The "active_table" contains the data that
* will start being used at the start of the next 20mS period. This keeps the pins
* well behaved during the transition.
*
* The ISR's priority is set to the maximum otherwise other ISRs can cause considerable
* jitter in the PWM high time.
*
* See the end of this file for details on the hardware/firmware interaction

/////////////////////////////////////////////////////////////////
/**
* Almost all changes to the hardware registers must be coordinated with the Match Register 0 (MR0)
* interrupt. The only exception is detaching pins. It doesn't matter when they go
* tristate.
*
* The LPC1768_PWM_init routine kicks off the MR0 interrupt. This interrupt is never disabled or
* delayed.
*
* The PWM_table_swap flag is set when the firmware has swapped in an updated table. It is
* cleared by the ISR during the MR0 interrupt as it completes the swap and accompanying updates.
* It serves two purposes:
* 1) Tells the ISR that the tables have been swapped
* 2) Keeps the firmware from starting a new update until the previous one has been completed.
*
* The PWM_MR0_wait flag is set when the firmware is ready to swap in an updated table and cleared by
* the ISR during the MR0 interrupt. It is used to avoid delaying the MR0 interrupt when swapping in
* an updated table. This avoids glitches in pulse width and/or repetition rate.
*
* The sequence of events during a write to a PWM channel is:
* 1) Waits until PWM_table_swap flag is false before starting
* 2) Copies the active table into the work table
* 3) Updates the work table
* NOTES - MR1-MR6 are updated at this time. The updates aren't put into use until the first
* MR0 after the LER register has been written. The LER register is written during the
* table swap process.
* - The MCR mask is created at this time. It is not used until the ISR writes the MCR
* during the MR0 interrupt in the table swap process.
* 4) Sets the PWM_MR0_wait flag
* 5) ISR clears the PWM_MR0_wait flag during the next MR0 interrupt
* 6) Once the PWM_MR0_wait flag is cleared then the firmware:
* disables the ISR interrupt
* swaps the pointers to the tables
* writes to the LER register
* sets the PWM_table_swap flag active
* re-enables the ISR
* 7) On the next interrupt the ISR changes its pointer to the work table which is now the old,
* unmodified, active table.
* 8) On the next MR0 interrupt the ISR:
* switches over to the active table
* clears the PWM_table_swap and PWM_MR0_wait flags
* updates the MCR register with the possibly new interrupt sources/assignments
* writes to the PCR register to enable the direct control of the Servo 0, 1 & 3 pins by the PWM1 module
* sets the PINSEL3 register to function/mode 0x2 for the Servo 0, 1 & 3 pins
* NOTE - PCR must be set before PINSEL
* sets the pins controlled by the ISR to their active states

/**
* Almost all changes to the hardware registers must be coordinated with the Match Register 0 (MR0)
* interrupt. The only exception is detaching pins. It doesn't matter when they go
* tristate.
*
* The LPC1768_PWM_init routine kicks off the MR0 interrupt. This interrupt is never disabled or
* delayed.
*
* The PWM_table_swap flag is set when the firmware has swapped in an updated table. It is
* cleared by the ISR during the MR0 interrupt as it completes the swap and accompanying updates.
* It serves two purposes:
* 1) Tells the ISR that the tables have been swapped
* 2) Keeps the firmware from starting a new update until the previous one has been completed.
*
* The PWM_MR0_wait flag is set when the firmware is ready to swap in an updated table and cleared by
* the ISR during the MR0 interrupt. It is used to avoid delaying the MR0 interrupt when swapping in
* an updated table. This avoids glitches in pulse width and/or repetition rate.
*
* The sequence of events during a write to a PWM channel is:
* 1) Waits until PWM_table_swap flag is false before starting
* 2) Copies the active table into the work table
* 3) Updates the work table
* NOTES - MR1-MR6 are updated at this time. The updates aren't put into use until the first
* MR0 after the LER register has been written. The LER register is written during the
* table swap process.
* - The MCR mask is created at this time. It is not used until the ISR writes the MCR
* during the MR0 interrupt in the table swap process.
* 4) Sets the PWM_MR0_wait flag
* 5) ISR clears the PWM_MR0_wait flag during the next MR0 interrupt
* 6) Once the PWM_MR0_wait flag is cleared then the firmware:
* disables the ISR interrupt
* swaps the pointers to the tables
* writes to the LER register
* sets the PWM_table_swap flag active
* re-enables the ISR
* 7) On the next interrupt the ISR changes its pointer to the work table which is now the old,
* unmodified, active table.
* 8) On the next MR0 interrupt the ISR:
* switches over to the active table
* clears the PWM_table_swap and PWM_MR0_wait flags
* updates the MCR register with the possibly new interrupt sources/assignments
* writes to the PCR register to enable the direct control of the Servo 0, 1 & 3 pins by the PWM1 module
* sets the PINSEL3 register to function/mode 0x2 for the Servo 0, 1 & 3 pins
* NOTE - PCR must be set before PINSEL
* sets the pins controlled by the ISR to their active states
