PWMKEY<15:0>: PWMx Unlock bits
If the PWMLOCK Configuration bit is asserted (PWMLOCK = 1), the PWMxCON1, PxFLTACON and
PxFLTBCON registers are writable only after the proper sequence is written to the PWMxKEY register. If the
PWMLOCK Configuration bit is deasserted (PWMLOCK = 0), the PWMxCON1, PxFLTACON and
PxFLTBCON registers are writable at all times. Refer to “Motor Control PWM” (DS70187) in the “dsPIC33/
PIC24 Family Reference Manual” for details on the unlock sequence.
