Timers

Timer 0 : 16-bit timer/counter with 2 capture registers.

Mode 0 : 8-bit timer with an 8-bit programmable prescaler (with two 8-bit capture registers)

 2 channels

Mode 1 : 8-bit timer with an 8-bit programmable prescaler (with two 8-bit capture registers)

+ 8-bit counter (with two 8-bit capture registers)

Mode 2 : 16-bit timer with an 8-bit programmable prescaler (with two 16-bit capture registers)

Mode 3 : 16-bit counter (with two 16-bit capture registers)

Timer 1 : 16-bit timer/counter that supports PWM/toggle outputs

Mode 0 : 8-bit timer with an 8-bit prescaler (with toggle outputs) + 8-bit timer/

counter with an 8-bit prescaler (with toggle outputs)

Mode 1 : 8-bit PWM with an 8-bit prescaler

 2 channels

Mode 2 : 16-bit timer/counter with an 8-bit prescaler (with toggle outputs)

(toggle outputs also possible from lower-order 8 bits)

Mode 3 : 16-bit timer with an 8-bit prescaler (with toggle outputs)

(lower-order 8 bits may be used as a PWM output)

Base timer

(1) The clock is selectable from the subclock (32.768kHz crystal oscillation), the low speed RC, system clock, and

timer 0 prescaler output.

(2) with an 8-bit programmable prescaler

(3) Interrupts programmable in 5 different time schemes
