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.
Same as CmpAUpd but for the comparator B register.
The Update mode for the comparator A register. If 0, updates to the
register are reflected to the comparator the next time the counter is 0.
If 1, 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 465).
The Update mode for the load register. If 0, updates to the register are
reflected to the counter the next time the counter is 0. If 1, 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.
The behavior of the counter in Debug mode. If 0, the counter stops
running when it next reaches 0, and continues running again when no
longer in Debug mode. If 1, the counter always runs.
The mode for the counter. If 0, the counter counts down from the load
value to 0 and then wraps back to the load value (Count-Down mode).
If 1, the counter counts up from 0 to the load value, back down to 0, and
then repeats (Count-Up/Down mode).
Master enable for the PWM generation block. If 0, the entire block is
disabled and not clocked. If 1, the block is enabled and produces PWM
signals.
