3) Baud rate: 16/3 to 8192/3 tCYC
„AD Converter: 8 bits × 12 channels
„PWM: Multifrequency 12-bit PWM × 2 channels
„Infrared Remote Control Receiver Circuit
1) Noise rejection function (noise filter time constant: Approx. 120μs when the 32.768kHz crystal oscillator is
selected as the base clock)
2) Supports data encoding systems such as PPM (Pulse Position Modulation) and Manchester encoding.
3) X'tal HOLD mode release function

3) Bit clock selectable:
48fs/64fs
4) Data bit length:
16/18/20/24 bits
5) LSB first/MSB first mode selectable
6) Left-justification/right-justification/I2S format selectable
„Watchdog Timer
• Watchdog timer using external RC circuitry
• Interrupt and reset signals selectable
„Clock Output Function
1) Can output a clock with a clock rate of 1/1, 1/2, 1/4, 1/8, 1/16, 1/32, or 1/64 of the source oscillator clock selected
as the system clock.
2) Can output the source oscillation clock for the subclock.
