8/16-bit PPG timer

Number of channels: 2 (four 8-bit channels are available also)

PPG operation is allowed with four 8-bit channels or one 16-bit channel.

Outputting pulse wave of arbitrary cycle or arbitrary duty is allowed.

Count clock: 62.5 ns to 1 µs

(with 16 MHz machine clock)

Delay interrupt generator

module

Interrupt generator module for task switching. Used for Real-time OS.

DTP/External interrupt

Number of inputs: 4

Activated by rising edge, falling edge, “H” level or “L” level input.

External interrupt or expanded intelligent I/O service (EI2OS) is available.

8/10-bit A/D converter

Number of channels: 8

Resolution: Selectable 10-bit or 8-bit.

Conversion time: 6.125 µs (at 16-MHz machine clock, including sampling time)

Sequential conversion of two or more successive channels is allowed. (Setting

a maximum of 8 channels is allowed.)

Single conversion mode : Selected channel is converted only once.

Sequential conversion mode: Selected channel is converted repetitively.

Halt conversion mode

: Conversion of selected channel is stopped and

activated alternately.

UART 1

Number of channels: 1

Clock-synchronous transfer: 62.5 Kbps to 2 Mbps

Clock-asynchronous transfer: 9,615 bps to 500 Kbps

Communication is allowed by bi-directional serial communication function and

master/slave type connection.
