14.3.2.21 PMF Counter A Register (PMFCNTA)
This register displays the state of the 15-bit PWM A counter.
14.3.2.22 PMF Counter Modulo A Register (PMFMODA)
The 15-bit unsigned value written to this register is the PWM period in PWM clock periods.
NOTE
The PWM counter modulo register is buffered. The value written does not
take effect until the LDOKA bit or global load OK is set and the next PWM
load cycle begins. Reading PMFMODA returns the value in the buffer. It is
not necessarily the value the PWM generator A is currently using.
14.3.2.23 PMF Deadtime A Register (PMFDTMA)
The 12-bit value written to this register is the number of PWM clock cycles in complementary channel
operation. A reset sets the PWM deadtime register to the maximum value of 0x0FFF, selecting a deadtime
