Register 16: PWM0 Compare A (PWM0CMPA), offset 0x058
This register contains a value to be compared against the counter . When this value matches the
counter, a pulse is output; this can drive the generation of a PWM signal (via the
PWMnGENA/PWMnGENB registers) or drive an interrupt (via the PWMnINTEN register). If the
value of this register is greater than the PWMnLOAD register (see page 423), then no pulse is ever
output.
If the comparator A update mode is immediate (based on the CmpAUpd bit in the PWMnCTL register),
then this 16-bit CompA value is used the next time the counter reaches zero. If the update mode is
synchronous, it is used the next time the counter reaches zero after a synchronous update has been
requested through the PWM Master Control (PWMCTL) register (see page 408). If this register is
rewritten before the actual update occurs, the previous value is never used and is lost.

Preliminary
Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Comparator A Value
The value to be compared against the counter.
