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) Timer1 : 16-bit counter timer 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 counter timer with an 8-bit prescaler (with toggle outputs) (toggle outputs also possible 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.) Timer4 : 8-bit timer with a 6-bit prescaler Timer5 : 8-bit timer with a 6-bit prescaler Timer6 : 8-bit timer with a 6-bit prescaler (with toggle output) Timer7 : 8-bit timer with a 6-bit prescaler (with toggle output) Timer8 : 16-bit timer Mode 0 : 8-bit timer with an 8-bit prescaler 2 channels Mode 1 : 16-bit timer with an 8-bit prescaler Base Timer 1) The clock is selectable from the subclock (32.768kHz crystal oscillation), system clock, and timer 0 prescaler output. 2) Interrupts programmable in 5 different time schemes Day and time counter 1) Used with a base timer, the day and time counter can be used as a 65000 day + minute + second counter. www.onsemi.com 2
