PWMKEY<15:0>: PWM Key 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 Section 47. “Motor Control PWM” (DS39735) in the “PIC24F Family Reference Manual”
for further details about the unlock sequence.
