(6) Asynchronous serial interface control register 6 (ASICL6)
192
Address: FF98H After reset: 16H R/W
ASICL6
Note Bit 7 is read-only.
Symbol
This register controls the serial communication operations of serial interface UART6.
ASICL6 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets this register to 16H.
Caution ASICL6 can be refreshed (the same value is written) by software during a communication
