compare register 5n (CR5n).
(TOE5n) of 8-bit timer mode control register 5n (TMC5n) to 1. This enables a square wave with any selected
frequency to be output (duty = 50%).
A square wave with any selected frequency is output at intervals determined by the value preset to 8-bit timer
The TO5n pin output status is inverted at intervals determined by the count value preset to CR5n by setting bit 0
