Optional flow control function (CTS and RTS)
Supports IrDA(SIR) function
Supports RS485 function
SPI
Up to two sets of SPI device.
Supports master/slave mode
Master mode clock rate up to 20 MHz, and slave mode clock rate up to 10 MHz
Full duplex synchronous serial data transfer
Variable length of transfer data from 1 to 32 bits
MSB or LSB first data transfer
Rx latching data can be either at rising edge or at falling edge of serial clock
Tx sending data can be either at rising edge or at falling edge of serial clock
Supports Byte suspend mode in 32-bit transmission
I
2C
Supports master/slave mode
Bidirectional data transfer between masters and slaves
Multi-master bus (no central master).
Arbitration between simultaneously transmitting masters without corruption of serial data
on the bus
Serial clock synchronization allows devices with different bit rates to communicate via
one serial bus.
Serial clock synchronization can be used as a handshake mechanism to suspend and
resume serial transfer.
Programmable clocks allow versatile rate control.
