cleared, while the TIDLEn, TXIFn and RIDLEn bits will be set. Other control bits in
UnCR1, UnCR2 and BRGn registers will remain unaffected. If the UARTn is active
and the UARTENn bit is cleared, all pending transmissions and receptions will be
terminated and the module will be reset as defined above. When the UARTn is re-
enabled, it will restart in the same configuration.
Bit 6 BNOn: Number of data transfer bits selection
0: 8-bit data transfer
1: 9-bit data transfer
This bit is used to select the data length format, which can have a choice of either
8-bit or 9-bit format. When this bit is equal to "1", a 9-bit data length format will be
selected. If the bit is equal to "0", then an 8-bit data length format will be selected. If
9-bit data length format is selected, then bits RX8n and TX8n will be used to store the
9th bit of the received and transmitted data respectively.
Bit 5 PRENn: Parity function enable control
0: Parity function is disabled
1: Parity function is enabled
This bit is the parity function enable bit. When this bit is equal to 1, the parity function
will be enabled. If the bit is equal to 0, then the parity function will be disabled.
Bit 4 PRTn: Parity type selection bit
0: Even parity for parity generator
1: Odd parity for parity generator
This bit is the parity type selection bit. When this bit is equal to 1, odd parity type will
be selected. If the bit is equal to 0, then even parity type will be selected.
Bit 3 STOPSn: Number of stop bits selection
0: One stop bit format is used
1: Two stop bits format is used
This bit determines if one or two stop bits are to be used. When this bit is equal to "1",
two stop bits format are used. If the bit is equal to "0", then only one stop bit format is
used.
TXBRKn: Transmit break character
Bit 2
0: No break character is transmitted
1: Break characters transmit
The TXBRKn bit is the Transmit Break Character bit. When this bit is equal to "0",
there are no break characters and the TXn pin operates normally. When the bit is
equal to "1", there are transmit break characters and the transmitter will send logic
zeros. When this bit is equal to "1", after the buffered data has been transmitted, the
transmitter output is held low for a minimum of a 13-bit length and until the TXBRKn
bit is reset.
Bit 1 RX8n: Receive data bit 8 for 9-bit data transfer format (read only)
This bit is only used if 9-bit data transfers are used, in which case this bit location
will store the 9
determine whether data transfers are in 8-bit or 9-bit format.
TX8n: Transmit data bit 8 for 9-bit data transfer format (write only)
Bit 0
This bit is only used if 9-bit data transfers are used, in which case this bit location
will store the 9
