14.4 Operation of Serial Interface UART6
14.4.1 Operation stop mode
addition, the pins can be used as ordinary port pins in this mode. To set the operation stop mode, clear bits 7, 6, and
5 (POWER6, TXE6, and RXE6) of ASIM6 to 0.
(1) Register used
Address: FF50H After reset: 01H R/W
Serial interface UART6 has the following two modes.
In this mode, serial communication cannot be executed; therefore, the power consumption can be reduced. In
Notes 1.
Caution Clear POWER6 to 0 after clearing TXE6 and RXE6 to 0 to stop the operation.
Remark To use the R
Symbol
ASIM6
The operation stop mode is set by asynchronous serial interface operation mode register 6 (ASIM6).
ASIM6 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets this register to 01H.

Asynchronous serial interface (UART) mode
2.
To start the communication, set POWER6 to 1, and then set TXE6 or RXE6 to 1.

Asynchronous serial interface reception error status register 6 (ASIS6), asynchronous serial interface
transmission status register 6 (ASIF6), bit 7 (SBRF6) and bit 6 (SBRT6) of asynchronous serial
interface control register 6 (ASICL6), and receive buffer register 6 (RXB6) are reset.
