11.3 Registers Controlling Serial Interface UART6
(1) Asynchronous serial interface operation mode register 6 (ASIM6)
Address: FF90H After reset: 01H R/W
Serial interface UART6 is controlled by the following nine registers.
Notes 1.
Symbol
ASIM6
This 8-bit register controls the serial communication operations of serial interface UART6.
This register can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets this register to 01H.
Remark ASIM6 can be refreshed (the same value is written) by software during a communication operation
