Table 26. W0MOD: PWMU0 Counter Mode Register
W0MOD - PWMU0 Counter Mode Register (E9h)
Reset Value = 00XX X000b
Not bit addressable
Because they use the same timer, all three modules have the same frequency deter-
mined by the shadow SW0F registers.

PWMU0 Module 2 inverter bit
Select the output PWM mode. If set, PWM module 2 output starts with high level.
PWMU0 Module 1 inverter bit
Select the output PWM mode. If set, PWM module 1 output starts with high level.
PWMU0 Module 0 inverter bit
Select the output PWM mode. If set, PWM module 0 output starts with high level.
PWMU0 high bits counter control frequency
The PWMU0 counter is counting from zero up to W1F15-0 value.
