15.2.3 PWM Width Register
The PWM width register (PWMWR) defines the width of the pulse in PCLKs. When
the counter matches the value in this register, the output is reset for the duration of
the period. Note that if the value in this register is not less than the period register, the
output will never be reset, resulting in a 100% duty cycle.
PWMWR0 — PWM0 Width Register
PWMWR1 — PWM1 Width Register
PWMWR2 — PWM2 Width Register
PWMWR3 — PWM3 Width Register
PWMWR4 — PWM4 Width Register
PWMWR5 — PWM5 Width Register

WIDTH — Pulse Width
When the counter reaches the value in this register, the output is reset.
15.2.4 PWM Counter Register
The read-only PWM counter register (PWMCTR) holds the current count value. It can
be read at any time without disturbing the counter.
PWMCTR0 — PWM0 Counter Register
PWMCTR1 — PWM1 Counter Register
PWMCTR2 — PWM2 Counter Register
PWMCTR3 — PWM3 Counter Register
PWMCTR4 — PWM4 Counter Register
PWMCTR5 — PWM5 Counter Register
