14.3 Registers Controlling Serial Interface UART6/DALI
Serial interface UART6/DALI is controlled by the following nine registers.
 In UART mode
 UART/DALI mode control register (UADLCTL)
 UART/DALI operation mode register 6 (ASIM6)
 UART/DALI reception error status register 6 (ASIS6)
 UART transmission status register 6 (ASIF6)
 Clock selection register 6 (CKSR6)
 Baud rate generator control register 6 (BRGC6)
 LIN operation control register 6 (ASICL6)
 Input switch control register (ISC)
 Port mode register 6 (PM6)
 Port register 6 (P6)
 Port output mode register 6 (POM6)
 In DALI mode
 UART/DALI mode control register (UADLCTL)
 UART/DALI operation mode register 6 (ASIM6)
 UART/DALI reception error status register 6 (ASIS6)
 Clock selection register 6 (CKSR6)
 Baud rate generator control register 6 (BRGC6)
 Port mode register 6 (PM6)
 Port output mode register 6 (POM6)
(1) UART/DALI mode control register (UADLCTL)
This is an 8-bit register that controls whether to operate serial interface UART6/DALI in UART mode or DALI mode.
This register can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets this register to 00H.
