Continued from preceding page.
⢠SIO9: Synchronous serial interface
1) LSB first/MSB first mode selectable
2) Transfer clock cycle: 4/3 to 1020/3 tCYC
3) Automatic continuous data transmission (1 to 4096 bytes, specifiable in 1 byte units)
(Suspension and resumption of data transmission possible in 1 byte units or word units)
4) Auto-start-on-falling-edge function
5) Clock polarity selectable
6) CRC16 calculator circuit built in
ÂFull Duplex UART
1) Data length: 7/8/9 bits selectable
2) Stop bits: 1 bit (2 bits in continuous transmission mode)
3) Baud rate: 16/3 to 8192/3 tCYC
ÂAD Converter: 8 bits à 12 channels
ÂPWM: Multifrequency 12-bit PWM Ã 2 channels
ÂInfrared 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 reset function
ÂUSB Interface (host control function)
1) Compliant with full-speed (12M bps) specifications
2) Supports 4 transfer types (control transfer, bulk transfer, interrupt transfer, and isochronous transfer).
ÂAudio Interface
1) Sampling frequency (fs):
32kHz, 44.1kHz, 48kHz
2) Master clock frequency (internal PLL): 12.288MHz, 16.9344MHz, 18.432MHz
3) Bit clock selectable:
48fs/64fs
4) Data bit length:
16/18/20/24 bits
5) LSB first/MSB firsts selectable
6) Left-justification/right-justification selectable
ÂWatchdog Timer
⢠Watchdog timer using external RC circuitry
⢠Interrupt and reset signals selectable
ÂClock 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.
