13.3 Registers Controlling Serial Interface UART0
(1) Asynchronous serial interface operation mode register 0 (ASIM0)
278
Address: FF70H After reset: 01H R/W
Serial interface UART0 is controlled by the following five registers.
Notes 1.
Symbol
ASIM0
This 8-bit register controls the serial communication operations of serial interface UART0.
This register can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets this register to 01H.
Asynchronous serial interface operation mode register 0 (ASIM0)
Asynchronous serial interface reception error status register 0 (ASIS0)
Baud rate generator control register 0 (BRGC0)
Port mode register 1 (PM1)
Port register 1 (P1)
