7.4.3 Square-wave output operation
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%).
204
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
<1> Set each register.
<2> After TCE5n = 1 is set, the count operation starts.
<3> The timer output F/F is inverted by a match of TM5n and CR5n. After INTTM5n is generated, TM5n is
<4> After these settings, the timer output F/F is inverted at the same interval and a square wave is output from
