(TOE50) of 8-bit timer mode control register 50 (TMC50) 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 TO50 pin output status is inverted at intervals determined by the count value preset to CR50 by setting bit 0
