Description (Continued)
Baud Rate Control
This bit causes an alternate UART behavior depending on the value of the REN bit in the
UART Control 0 Register. When the UART receiver is not enabled (REN=0), this bit deter-
mines whether the Baud Rate Generator issues interrupts.
0 = Reads from the Baud Rate High and Low Byte registers return the BRG reload value.
1 = The Baud Rate Generator generates a receive interrupt when it counts down to 0.
When the UART receiver is enabled (REN=1), this bit allows reads from the Baud Rate reg-
isters to return the BRG count value instead of the reload value.
0 = Reads from the Baud Rate High and Low Byte registers return the BRG reload value.
1 = Reads from the Baud Rate High and Low Byte registers return the current BRG count
Receive Data Interrupt Enable
0 = Received data and receiver errors generates an interrupt request to the Interrupt Con-
1 = Received data does not generate an interrupt request to the Interrupt Controller. Only
Infrared Encoder/Decoder Enable
0 = Infrared Encoder/Decoder is disabled. UART operates normally.
1 = Infrared Encoder/Decoder is enabled. The UART transmits and receives data through
Reads from the Baud Rate High and Low Byte registers return the current BRG count
