SIO

 SIO0: Synchronous serial interface

1) LSB first/MSB first mode selectable

2) Transfer clock cycle: 4/3 to 512/3 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)

 SIO4: 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 2048 bytes, specifiable in 1 byte units, suspension and resumption

of data transmission possible in 1 byte or 2 bytes units)

4) Auto-start-on-falling-edge function

5) Clock polarity selectable

6) CRC16 calculator circuit built in



Full Duplex UART
