No.A0858-3/24

•

High-speed Clock Counter

1) Can count clocks with a maximum clock rate of 20MHz (at a main clock of 10MHz).

2) Can generate output real-time.

•

SIO

• SIO0: 8-bit synchronous serial interface

1) LSB first/MSB first mode selectable

2) Built-in 8-bit baudrate generator (maximum transfer clock cycle = 4/3 tCYC)

3) Automatic continuous data transmission (1 to 256 bits specifiable in 1-bit units, suspension and resumption of

data transmission possible in 1-byte units)

• SIO1: 8-bit asynchronous/synchronous serial interface

Mode 0: Synchronous 8-bit serial I/O (2- or 3-wire configuration, 2 to 512 tCYC transfer clocks)

Mode 1: Asynchronous serial I/O (half-duplex, 8-data bits, 1-stop bit, 8 to 2048 tCYC baudrates)

Mode 2: Bus mode 1 (start bit, 8-data bits, 2 to 512 tCYC transfer clocks)

Mode 3: Bus mode 2 (start detect, 8-data bits, stop detect)

•

UART

• Full duplex

• 7/8/9 bit data bits selectable

• 1 stop bit (2-bit in continuous data transmission)

• Built-in baudrate generator

* When using UART, set P0LDDR (PODDR: Bit0) to “0”

•

AD Converter: 12 bits

× 12 channels

•

PWM: Multi frequency 12-bit PWM

× 2 channels

•

Infrared Remote Control Receiver Circuit

1) Noise reduction function

(Time constant of noise reduction filter: approx. 120

μs, when selecting a 32.768kHz crystal oscillator as a

reference clock.)

2) X’tal HOLD mode cancellation function

•

Watchdog Timer

• External RC watchdog timer

• Interrupt and reset signals selectable

•

Clock Output Function

1) Can output selected oscillation clock 1/1, 1/2, 1/4, 1/8, 1/16, 1/32, or 1/64 as system clock.

2) Can output the source oscillation clock for the sub clock.
