0 : No framing error
1 : Framing error found
0 : No parity error
1 : Parity error found
0 : No error
1 : Error found
Note: Bits 15 through 12 are set to “0” when the serial I/O mode select bit (bits 2 to 0 at addresses
03A016 and 03A816) are set to “0002” or the receive enable bit is set to “0”.
(Bit 15 is set to “0” when bits 14 to 12 all are set to “0”.) Bits 14 and 13 are also set to “0” when
the lower byte of the UARTi receive buffer register (addresses 03A616 and 03AE16) is read out.
