CHAPTER 11 SERIAL INTERFACE UART6
(6) Asynchronous serial interface control register 6 (ASICL6)
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.
Generation of reset signal sets this register to 16H.
Caution ASICL6 can be refreshed (the same value is written) by software during a communication
operation (when bit 7 (POWER6) and bit 6 (TXE6) of ASIM6 are 1 or when bit 7 (POWER6) and
bit 5 (RXE6) of ASIM6 are 1), if 0 data has been written to ASICL6 by SBRT6 and SBTT6.
