The PWMA1 register contains the period value for the next cycle of the PWM output
waveform. When the PWMSM is enabled, a period value written to PWMA1 is loaded
into PWMA2 at the end of the current period or when the LOAD bit in PWMSIC is writ-
ten to one. If the PWMSM is disabled, a period value written to PWMA1 is loaded into
PWMA2 on the next half cycle of the MCU system clock. PWMA2 is a temporary reg-
ister that is used to smoothly update the PWM period value; it is not user-accessible.
The PWMSM hardware does not modify the contents of PWMA1 at any time.
