RESET:
The PWMB1 register contains the pulse width value for the next cycle of the PWM out-
put waveform. When the PWMSM is enabled, a pulse width value written to PWMB1
is loaded into PWMB2 at the end of the current period or when the LOAD bit in PWM-
SIC is written to one. If the PWMSM is disabled, a pulse width value written to PWMB1
is loaded into PWMB2 on the next half cycle of the MCU system clock. PWMB2 is a
temporary register that is used to smoothly update the PWM pulse width value; it is not
user-accessible. The PWMSM hardware does not modify the contents of PWMB1 at
any time.
PWMC holds the current value of the PWMSM counter. PWMC can be read at any
time; writing to it has no effect. PWMC is loaded with $0001 on reset and is set and
held to that value whenever the PWMSM is disabled.
