(7) LIN operation 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.

Cautions1. ASICL6 is not used in DALI mode (UADLSEL = 1). In DALI mode, even if the SBRT6, SBTT6,

SBL62 to SBL60, DIR6, and TXDLV6 bits are set, the set contents are invalid. The read value of

the SBRF6 bit is 0.

2. 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.
