PWPERx — PWM Channel Period Registers  
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)
