Load Frequency C — This field selects the PWM load frequency according to
Section 11.4.7.2, “Load Frequency”
Note: The LDFQC field takes effect when the current load cycle is complete, regardless of the state of the load
Half Cycle Reload C — This bit enables half-cycle reloads in center-aligned PWM mode. This bit has no effect
on edge-aligned PWMs.
0 Half-cycle reloads disabled
1 Half-cycle reloads enabled
Prescaler C — This buffered field selects the PWM clock frequency illustrated in
Note: Reading the PRSCC field reads the buffered value and not necessarily the value currently in effect. The
PWM Reload Flag C — This flag is set at the beginning of every reload cycle regardless of the state of the
LDOKC bit. Clear PWMRFC by reading PMFFQCC with PWMRFC set and then writing a logic one to the
PWMRFC bit. If another reload occurs before the clearing sequence is complete, writing logic one to PWMRFC
has no effect.
0 No new reload cycle since last PWMRFC clearing
1 New reload cycle since last PWMRFC clearing
Note: Clearing PWMRFC satisfies pending PWMRFC CPU interrupt requests.

PRSCC field takes effect at the beginning of the next PWM cycle and only when the load okay bit, LDOKC,
is set.
