Timer 2 Mode Register 1
(T2M1)
Duty Cycle Generator
4554A–4BMCU–02/03
The duty cycle generator generates duty cycles of 25%, 33% or 50%. The frequency at
the duty cycle generator output depends on the duty cycle and the Timer 2 prescaler
setting. The DCG-stage can also be used as additional programmable prescaler for
Timer 2.

Timer 2 Modes
12-bit compare counter; the
DCG has to be bypassed in
this mode
8-bit compare counter with
4-bit programmable prescaler
and duty cycle generator
8-bit compare counter clocked
by SYSCL or the external clock
input T2I, 4-bit prescaler run,
the counter 2/1 starts after
writing mode 3
8-bit compare counter clocked
by SYSCL or the external clock
input T2I, 4-bit prescaler stop
and resets
