Reserved—Must be 0
NEWFRM—Status bit denoting the start of a new frame. Reading the UART Receive
Data Register resets this bit to 0.
0 = The current byte is not the first data byte of a new frame.
1 = The current byte is the first data byte of a new frame.
MPRX—Multiprocessor Receive
Returns the value of the last multiprocessor bit received. Reading from the UART Receive
Data Register resets this bit to 0.
The UART Control 0 and Control 1 registers
ure the properties of the UART’s transmit and receive operations. The UART Control
Registers must not been written while the UART is enabled.
TEN—Transmit Enable
This bit enables or disables the transmitter. The enable is also controlled by the CTS signal
and the CTSE bit. If the CTS signal is low and the CTSE bit is 1, the transmitter is
enabled.
0 = Transmitter disabled.
1 = Transmitter enabled.
REN—Receive Enable
This bit enables or disables the receiver.
0 = Receiver disabled.
1 = Receiver enabled.
CTSE—CTS Enable
0 = The CTS signal has no effect on the transmitter.
1 = The UART recognizes the CTS signal as an enable control from the transmitter.
PEN—Parity Enable
This bit enables or disables parity. Even or odd is determined by the PSEL bit. This bit is
overridden by the
0 = Parity is disabled.
1 = The transmitter sends data with an additional parity bit and the receiver
receives an additional parity bit.
