14.1 Features
14.1.1 Operation Modes
This device has three serial I/O channels: SIO0 to SIO2.
Four operation modes (mode 0 through mode 3) are provided to SIO. Table 14.1 shows data format of each
mode.
Mode 0 is to send and receive I/O data and associated synchronization signals (SCLK) to extend I/O. SCLK
can be used for input and output.
You can select either of LSB or MSB to send first. Neither adding parity nor stop bit is available.
Modes 1 through 3 execute asynchronous communication and are designed to send LSB first.
In the modes 1 and 2, parity bits can be added. The mode 3 has a wakeup function in which the master
controller can start up slave controllers via the serial link (multi-controller system).
Stop bit length at transmission can be selected from 1 bit or 2 bits. At reception, stop bit is 1 bit.
Hereinafter synchronous mode is referred to as I/O interface mode, asynchronous mode is referred to as
UART mode or 7 bit/ 8 bit/ 9 bit UART mode, which includes TX/RX data length.
