12.4 Serial Interface 20 Operation

Serial interface 20 provides the following three modes.

•

Operation stop mode

•

Asynchronous serial interface (UART) mode

•

3-wire serial I/O mode

12.4.1 Operation stop mode

In operation stop mode, serial transfer is not executed, thereby reducing the power consumption. The

P23/SCK20/ASCK20, P24/SO20/TxD20, and P25/SI20/RxD20 pins can be used as normal I/O ports.

(1)

Register setting

Operation stop mode is set by serial operation mode register 20 (CSIM20) and asynchronous serial

interface mode register 20 (ASIM20).

(a) Serial operation mode register 20 (CSIM20)

CSIM20 is set with a 1-bit or 8-bit memory manipulation instruction.

RESET input clears CSIM20 to 00H.
