Read and write anytime.
The value in the period register determines the period of the associated
PWM channel. If written while the channel is enabled, the new value will
not take effect until the existing period terminates, forcing the counter to
reset. The new period is then latched and is used until a new period
value is written. Reading this register returns the most recent value
written. To start a new period immediately, write the new period value
and then write the counter forcing a new period to start with the new
period value.
Period = Channel-Clock-Period × (PWPER + 1)
Period = Channel-Clock-Period × (2 × PWPER)
