This section explains the three modes of serial interface UART0.
Because serial transfer is not performed in this mode, the power consumption can be reduced.
In addition, pins can be used as ordinary ports.
This mode enables full-duplex operation wherein one byte of data after the start bit is transmitted or received.
The on-chip baud rate generator dedicated to UART enables communications using a wide range of selectable
The UART baud rate generator can also be used to generate a MIDI-standard baud rate (31.25 kbps).
Address: FFA0H After reset: 00H
Operation stop mode is set by asynchronous serial interface mode register 0 (ASIM0).
ASIM0 is set by a 1-bit or 8-bit memory manipulation instruction.
RESET input clears ASIM0 to 00H.
• Asynchronous serial interface mode register 0 (ASIM0)
• Asynchronous serial interface status register 0 (ASIS0)
• Baud rate generator control register 0 (BRGC0)
• Port mode register 2 (PM2)
• Port 2 (P2)
