TMC5n.
Note The initial value of TO5n output can be set by bits 2 and 3 (LVR5n, LVS5n) of 8-bit timer mode control
8-bit timer/event counter 5n operates as a PWM output when bit 6 (TMC5n6) of 8-bit timer mode control register 5n
The duty pulse determined by the value set to 8-bit timer compare register 5n (CR5n) is output from TO5n.
Set the active level width of the PWM pulse to CR5n; the active level can be selected with bit 1 (TMC5n1) of
The count clock can be selected with bits 0 to 2 (TCL5n0 to TCL5n2) of timer clock selection register 5n (TCL5n).
PWM output can be enabled/disabled with bit 0 (TOE5n) of TMC5n.
