14.3 Registers Controlling Serial Interfaces UART60 and UART61
(1) Asynchronous serial interface operation mode register 6n (ASIM6n)
316
Serial interfaces UART60 and UART61 are controlled by the following nine registers.
• Asynchronous serial interface operation mode register 6n (ASIM6n)
• Asynchronous serial interface reception error status register 6n (ASIS6n)
• Asynchronous serial interface transmission status register 6n (ASIF6n)
• Clock selection register 6n (CKSR6n)
• Baud rate generator control register 6n (BRGC6n)
• Asynchronous serial interface control register 6n (ASICL6n)
• Input switch control register (ISC)
• Port mode register 1 (PM1)
• Port register 1 (P1)
This 8-bit register controls the serial communication operations of serial interface UART60 and UART61.
This register can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets this register to 01H.
Remarks 1. ASIM6n can be refreshed (the same value is written) by software during a communication
2. n = 0, 1
operation (when bits 7 and 6 (POWER6n, TXE6n) of ASIM6n = 1 or bits 7 and 5 (POWER6n,
RXE6n) of ASIM6n = 1).
