Register 31: PWM0 Compare B (PWM0CMPB), offset 0x05C
Register 32: PWM1 Compare B (PWM1CMPB), offset 0x09C
Register 33: PWM2 Compare B (PWM2CMPB), offset 0x0DC
These registers contain a value to be compared against the counter (PWM0CMPB controls the
PWM generator 0 block, and so on). 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 or ADC trigger (via the PWMnINTEN register). If the value of this register is greater than
the PWMnLOAD register, no pulse is ever output.
If the comparator B update mode is immediate (based on the CmpBUpd bit in the PWMnCTL register),
this 16-bit CompB 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 484). If this register is
rewritten before the actual update occurs, the previous value is never used and is lost.

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 B Value
The value to be compared against the counter.
