14.3 Registers Controlling Serial Interface UART6
Serial interface UART6 is controlled by the following ten registers.
• Asynchronous serial interface operation mode register 6 (ASIM6)
• Asynchronous serial interface reception error status register 6 (ASIS6)
• Asynchronous serial interface transmission status register 6 (ASIF6)
• Clock selection register 6 (CKSR6)
• Baud rate generator control register 6 (BRGC6)
• Asynchronous serial interface control register 6 (ASICL6)
• Input switch control register (ISC)
• Port mode register 1 (PM1), port mode register 6 (PM6)
Note 1
• Port register 1 (P1), port register 6 (P6)
Note 1
• Port output mode register 6 (POM6)
Note 2
Notes 1. 78K0/KY2-L, 78K0/KA2-L: Port mode register 6 (PM6), port register 6 (P6)
78K0/KB2-L, 78K0/KC2-L: Port mode register 1 (PM1), port register 1 (P1)
2. In the 78K0/KY2-L and 78K0/KA2-L, this register is used when using serial interface UART6.
(1) Asynchronous serial interface operation mode register 6 (ASIM6)
This 8-bit register controls the serial communication operations of serial interface UART6.
This register can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets this register to 01H.
Remark ASIM6 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).
