(2) Asynchronous serial interface reception error status register 6 (ASIS6)
364
Address: FF53H After reset: 00H R
Cautions 1. The operation of the PE6 bit differs depending on the set values of the PS61 and PS60 bits of
Symbol
ASIS6
This register indicates an error status on completion of reception by serial interface UART6. It includes three
error flag bits (PE6, FE6, OVE6).
This register is read-only by an 8-bit memory manipulation instruction.
Reset signal generation, or clearing bit 7 (POWER6) or bit 5 (RXE6) of ASIM6 to 0 clears this register to 00H.
00H is read when this register is read. If a reception error occurs, read ASIS6 and then read receive buffer
register 6 (RXB6) to clear the error flag.

2. For the stop bit of the receive data, only the first stop bit is checked regardless of the number
3. If an overrun error occurs, the next receive data is not written to receive buffer register 6
4. If data is read from ASIS6, a wait cycle is generated. Do not read data from ASIS6 when the
