Register 10: PWM0 Control (PWM0CTL), offset 0x040
Register 11: PWM1 Control (PWM1CTL), offset 0x080
Register 12: PWM2 Control (PWM2CTL), offset 0x0C0
These registers configure the PWM signal generation blocks (PWM0CTL controls the PWM generator
0 block, and so on). The Register Update mode, Debug mode, Counting mode, and Block Enable
mode are all controlled via these registers. The blocks produce the PWM signals, which can be
either two independent PWM signals (from the same counter), or a paired set of PWM signals with
dead-band delays added.
The PWM0 block produces the PWM0 and PWM1 outputs, the PWM1 block produces the PWM2 and
PWM3 outputs, and the PWM2 block produces the PWM4 and PWM5 outputs.

DescriptionResetTypeNameBit/Field
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 Update Mode
Same as CmpAUpd but for the comparator B register.
0R/WCmpBUpd5
Comparator A Update Mode
The Update mode for the comparator A register. When not set, updates
to the register are reflected to the comparator the next time the counter
is 0. When set, updates to the register are delayed until the next time
the counter is 0 after a synchronous update has been requested through
the PWM Master Control (PWMCTL) register (see page 669).
0R/WCmpAUpd4
Load Register Update Mode
The Update mode for the load register. When not set, updates to the
register are reflected to the counter the next time the counter is 0. When
set, updates to the register are delayed until the next time the counter
is 0 after a synchronous update has been requested through the PWM
Master Control (PWMCTL) register.
0R/WLoadUpd3
Debug Mode
The behavior of the counter in Debug mode. When not set, the counter
stops running when it next reaches 0, and continues running again when
no longer in Debug mode. When set, the counter always runs.
