13.4 Operation of Serial Interface UART0
13.4.1 Operation stop mode
pins can be used as ordinary port pins in this mode. To set the operation stop mode, clear bits 7, 6, and 5 (POWER0,
TXE0, and RXE0) of ASIM0 to 0.
(1) Register used
Address: FF70H After reset: 01H R/W
Serial interface UART0 has the following two modes.
In this mode, serial communication cannot be executed, thus reducing the power consumption. In addition, the
Notes 1.
Caution Clear POWER0 to 0 after clearing TXE0 and RXE0 to 0 to set the operation stop mode.
Remark To use the RxD0/SI10/P11 and TxD0/SCK10/P10 pins as general-purpose port pins, see CHAPTER 4
Symbol
ASIM0
The operation stop mode is set by asynchronous serial interface operation mode register 0 (ASIM0).
ASIM0 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets this register to 01H.
Operation stop mode
Asynchronous serial interface (UART) mode

To start the communication, set POWER0 to 1, and then set TXE0 or RXE0 to 1.
