timer

2 channels

8-bit one-shot timer operation (supports underflow output, operating clock period : 1, 4, 32

tinst*, external)

8-bit reload timer operation (supports square wave output, operating clock period : 1, 4,

32 tinst*, external)

8-bit pulse width measurement operation (supports continuous measurement, H width, L

width, rising edge to rising edge, falling edge to falling edge measurement and both edge

measurement)

PWM timer

8-bit reload timer operation (supports square wave output, operating clock period : 1, 4,

32 tinst*, external)

8-bit resolution PWM operation

8/16-bit timer/

counter 1, 2

Can be operated either as a 2-channel 8-bit timer/counter (Timer 1 and Timer 2, each with

its own independent operating clock cycle) , or as one 16-bit timer/counter

In Timer 1 or 16-bit timer/counter operation, event counter operation (external clock-trig-

gered) and square wave output capable

8/16-bit timer/

counter 3, 4

Can be operated either as a 2-channel 8-bit timer/counter (Timer 3 and Timer 4, each with

its own independent operating clock cycle) , or as one 16-bit timer/counter

In Timer 3 or 16-bit timer/counter operation, event counter operation (external clock-trig-

gered) and square wave output capable

External interrupt

4 independent channels (selectable edge, interrupt vector, request flag)

5 channels (low level interrupt)
