Ports

General-purpose I/O ports (CMOS) : 21 (also serve as peripherals )

(4 ports are also an N-ch open-drain type.)

21-bit time

base timer

21-bit Interrupt cycle : 0.82 ms, 3.3 ms, 26.2 ms, or 419.4 ms with 10-MHz main clock

Watching timer

Reset generation cycle : 419.4 ms minimum with 10-MHz main clock

8-bit PWM timer

8-bit interval timer operation (square output capable, operating clock cycle :

0.4 µs , 3.2 µs, 6.4 µs, 25.6 µs)

8-bit resolution PWM operation (conversion cycle : 102.4 µs to 26.84 s : in the selection of

internal shift clock of 8/16-bit capture timer)

Count clock selectable between 8-bit and 16-bit timer/counter outputs

8/16-bit capture,

timer/counter

8-bit capture timer/counter × 1 channel + 8-bit timer or

16-bit capture timer/counter × 1 channel

Capable of event count operation and square wave output using external clock input with

8-bit timer 0 or 16-bit counter

UART

Transfer data length : 6/7/8 bits

8-bit Serial I/O

8 bits LSB first/MSB first selectable

One clock selectable from four operation clocks

(one external shift clock, three internal shift clocks : 0.8 µs, 6.4 µs, 25.6 µs)

12-bit PPG timer

External interrupt 1

(wake-up function)

3 channels (Interrupt vector, request flag, request output enabled)

Edge selectable (Rising edge, falling edge, or both edges)

Also available for resetting stop/sleep mode (Edge detectable even in stop mode)

External interrupt 2

(wake-up function)

1 channel with 8 inputs (Independent L-level interrupt and input enable)

Also available for resetting stop/sleep mode (Level detectable even in stop mode)
