9.4.4 8-bit PWM output operation
5n (TMC5n) is set to 1.
Note The TO5n output initial value can be set by bits 2 and 3 (LVR5n, LVS5n) of 8-bit timer mode control register
Remarks 1. N = 00H to FFH
The 8-bit timer/event counter operates as PWM output when bit 6 (TMC5n6) of 8-bit timer mode control register
The duty ratio pulse is determined by the value set to 8-bit timer compare register 5n (CR5n).
Set the active level width of the PWM pulse to CR5n. The active level can be selected with bit 1 (TMC5n1) of TMC5n.
The count clock can be selected with bits 0 to 2 (TCL5n0 to TCL5n2) of timer clock select register 5n (TCL5n).
PWM output enable/disable can be selected with bit 0 (TOE5n) of TMC5n.
Caution CR5n can be rewritten in PWM mode only once per cycle.
