Field Description
TDFL
Transmitter Data Field length
This field sets the number of bytes to be transmitted in UART mode. It can be programmed
only when the UART bit is set. TDFL[0:1] = Transmit buffer size – 1.
00 Transmit buffer size = 1.
01 Transmit buffer size = 2.
10 Transmit buffer size = 3.
11 Transmit buffer size = 4.
RDFL
Receiver Data Field length
This field sets the number of bytes to be received in UART mode. It can be programmed only
when the UART bit is set. RDFL[0:1] = Receive buffer size – 1.
00 Receive buffer size = 1.
01 Receive buffer size = 2.
10 Receive buffer size = 3.
11 Receive buffer size = 4.
RXEN
Receiver Enable
0 Receiver disable.
1 Receiver enable.
This bit can be programmed only when the UART bit is set.
TXEN
Transmitter Enable
0 Transmitter disable.
1 Transmitter enable.
This bit can be programmed only when the UART bit is set.
Note: Transmission starts when this bit is set and when writing DATA0 in the BDRL
register.
OP
Odd Parity
0 Sent parity is even.
1 Sent parity is odd.
This bit can be programmed in Initialization mode only when the UART bit is set.
PCE
Parity Control Enable
0 Parity transmit/check disable.
1 Parity transmit/check enable.
This bit can be programmed in Initialization mode only when the UART bit is set.
WL
Word Length in UART mode
0 7-bit data + parity bit.
1 8-bit data (or 9-bit if PCE is set).
This bit can be programmed in Initialization mode only when the UART bit is set.
UART
UART mode enable
0LIN mode.
1UART mode.
This bit can be programmed in Initialization mode only.
