PMF Value 2 Bits — The 16-bit signed value in this buffered register is the pulse width in PWM2 clock period.
A value less than or equal to zero deactivates the PWM output for the entire PWM period. A value greater than,
or equal to the modulus, activates the PWM output for the entire PWM period. See
activate and deactivate refer to the high and low logic states of the PWM output.
Note: PMFVAL2 is buffered. The value written does not take effect until the LDOK bit is set and the next PWM
PMF Value 3 Bits — The 16-bit signed value in this buffered register is the pulse width in PWM3 clock period.
A value less than or equal to zero deactivates the PWM output for the entire PWM period. A value greater than,
or equal to the modulus, activates the PWM output for the entire PWM period. See
activate and deactivate refer to the high and low logic states of the PWM output.
