PMFVAL4
PMF Value 4 Bits — The 16-bit signed value in this buffered register is the pulse width in PWM4 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 Table 11-46. The terms
activate and deactivate refer to the high and low logic states of the PWM output.
Note: PMFVAL4 is buffered. The value written does not take effect until the LDOK bit is set and the next PWM
load cycle begins. Reading PMFVAL4 reads the value in the buffer and not necessarily the value the PWM
generator is currently using.

PMFVAL5
PMF Value 5 Bits — The 16-bit signed value in this buffered register is the pulse width in PWM5 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 Table 11-46. The terms
activate and deactivate refer to the high and low logic states of the PWM output.
Note: PMFVAL5 is buffered. The value written does not take effect until the LDOK bit is set and the next PWM
load cycle begins. Reading PMFVAL5 reads the value in the buffer and not necessarily the value the PWM
generator is currently using.
