14.3 Registers Controlling Serial Interface UART00
(1) Asynchronous serial interface operation mode register 00 (ASIM00)
Address: FF70H After reset: 01H R/W
ASIM00
Serial interface UART00 is controlled by the following five registers.
Notes 1.
Symbol
This 8-bit register controls the serial communication operations of serial interface UART00.
This register can be set by a 1-bit or 8-bit memory manipulation instruction.
RESET input sets this register to 01H.
Asynchronous serial interface operation mode register 00 (ASIM00)
Asynchronous serial interface reception error status register 00 (ASIS00)
Baud rate generator control register 00 (BRGC00)
Port mode register 1 (PM1)
Port register 1 (P1)

POWER00
POWER00
The input from the RxD00 pin is fixed to high level when POWER00 = 0.
Asynchronous serial interface reception error status register 00 (ASIS00), transmit shift register 00
(TXS00), and receive buffer register 00 (RXB00) are reset.
