Interrupt requests are generated at 0.5-second intervals. (A clock timer oscillator is

incorporated.)

Either the main clock (12.58 MHz) or real-timer clock (32.768 kHz) can be selected as the

input clock.

Selected from fCLK, fCLK/2, fCLK/4, fCLK/8, or fCLK/16 (can be used as a 1-bit output port)

12-bit resolution × 2 channels

UART/IOE (3-wire serial I/O) : 2 channels (incorporating baud rate generator)

CSI (3-wire serial I/O)

: 2 channels

Note Additional function pins are included in the I/O pins.
