Serial Interface
1. Features
The serial interface (SIO) performs both clock synchronized and start-stop transfers.
2. SIO Functions
2.1 Port Configuration
• Independent transmit and receive circuits
• Double buffer configuration for receive buffer
Because the transmit and receive circuits are independent, start-stop transfers are all full-duplex
communication.
2.2 Transfer Methods
• Start-stop transfer
Data length:
Transfer sequence:
Stop bits:
Parity bit:
Flag bit:
7 bits or 8 bits selectable
LSB first
1 bit or 2 bits selectable
No parity, even parity, or odd parity selectable
Enables inter-processor communication using the serial port.
However, cannot be used together with parity bit.
• Clock synchronized transfer
Data length:
8 bits fixed
Transfer sequence: LSB first
