(6) LIN operation control register 0 (ASICL0)
The ASICL0 register is an 8-bit register that controls the output format for SBF transmission/reception and
transmission.
This register can be read or written in 8-bit or 1-bit units.
Reset sets this register to 16H.
Cautions 1. The ASICL0 register is valid only for UART0. UART1 does not support this register.
2. The same value is written to the ASICL0 register by software during a communication

Note The SBRF0 bit is read-only.

operation (when ASIM0.UARTE0 bit = 1 and ASIM0.TXE0 bit = 1, or ASIM0.UARTE0 bit =
1 and ASIM0.RXE0 bit = 1). However, do not set the SBRT0 bit = 1 or SBTT0 bit = 1 by
writing the same value during SBF reception (SBRF0 bit = 1) or SBF transmission (until
INTST0 interrupt occurs since SBTT0 bit has been set to 1), because it may re-trigger
SBF reception or SBF transmission.
