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.

 Serial Interfaces

SIO0: 8-bit synchronous serial interface

1) LSB first/MSB first made selectable

2) Built-in 8-bit baudrate generator (maximum transfer clock cycle

 4/3tCYC)

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)

 Infrared Remote Control Receiver Circuit1

1) Noise reduction function (Time constant of noise reduction filter: approx. 120

s, when selecting a 32.768kHz

crystal oscillator as a reference clock)

2) Supporting reception formats with a guide-pulse of half-clock/clock/none.

3) Determines a end of reception by detecting a no-signal periods (No carrier).

(Supports same reception format with a different bit length.)

4) X’tal HOLD mode cancellation function

Infrared Remote Control Receiver Circuit2

1) Noise reduction function

(Time constant of noise reduction filter: approx. 120μs, when selecting a 32.768kHz crystal oscillator as a

reference clock.)

2) Supporting reception formats with a guide-pulse of half-clock/clock/none.

3) Determines a end of reception by detecting a no-signal periods (No carrier).

(Supports same reception format with a different bit length.)

4) X’tal HOLD mode cancellation function

Watchdog Timer

1) External RC watchdog timer

2) 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 a system clock.

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