If the PWMLOCK input signal is asserted (PWMLOCK = 1), the PWMxCON1, PxFLTACON and PxFLTBCON
registers are writable only after the proper sequence is written to the PWMKEY register. If the PWMLOCK
input signal is deasserted (PWMLOCK = 0), the PWMxCON1, PxFLTACON and PxFLTBCON registers are
writable at all times. Refer to Section 47.14.4 Write-Protected Registers for further details about the
unlock sequence.
