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)

+ 8-bit timer/counter (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 from the lower-order 8 bits)

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

(The lower-order 8 bits can be used as PWM.)

- Timer 7: 8-bit timer with a 6-bit prescaler (with toggle outputs)

- Base timer

1) The clock is selectable from the subclock (32.768 kHz crystal oscillator), system clock, and timer 0

prescaler output.

2) Interrupts programmable in 5 different time schemes.

High-speed Clock Counter

1) Can count clocks with a maximum clock rate of 20MHz (at a main clock of 10MHz).

2) Can generate output real time.
