(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.

Reset signal generation sets this register to 16H.

Caution ASICL6 can be refreshed (the same value is written) by software during a communication operation

(when bits 7 and 6 (POWER6, TXE6) of ASIM6 = 1 or bits 7 and 5 (POWER6, RXE6) of ASIM6 = 1).

However, do not set both SBRT6 and SBTT6 to 1 by a refresh operation during SBF reception

(SBRT6 = 1) or SBF transmission (until INTST6 occurs since SBTT6 has been set (1)), because it

may re-trigger SBF reception or SBF transmission.
