Description
USART 0 mode select
0 SPI mode
1 UART mode
UART 0 receiver enable
0 Receiver disabled
1 Receiver enabled
SPI 0 master or slave mode select
0 SPI master
1 SPI slave
UART 0 framing error status
0 No framing error detected
1 Byte received with incorrect stop bit level
Note: TCON.URX0IF and U0CSR.RX_BYTE bit will be asserted when
the first stop bit is checked OK, meaning that if two stop bits are sent and
the second stop bit is not OK, this bit is asserted 1 bit duration later than
the 2 other above mentioned bits.
UART 0 parity error status
0 No parity error detected
1 Byte received with parity error
Receive byte status
0 No byte received
1 Received byte ready
Transmit byte status
0 Byte not transmitted
1 Last byte written to Data Buffer register transmitted
USART 0 transmit/receive active status
0 USART 0 idle
1 USART 0 busy in transmit or receive mode
