Baud Rate Divisor bits [7:0]. Least significant byte of baud
rate divisor. These bits are cleared to 0 on reset. The baud
rate divisor is calculated as follows:
Baud rate divisor BAUDDIV = (F
rate)) –1
where F
baud rate divisor of zero is not allowed and will result in no
data transfer.
Reserved. Unknown During Read.
Loopback Enable. If this bit is set to 1, data sent to TXD is
received on RXD. This bit is cleared to 0 on reset, which
disables the loopback mode.
Receive Timeout Enable. If this bit is set to 1, the receive
timeout interrupt is enabled.
Transmit Interrupt Enable. If this bit is set to 1, the transmit
interrupt is enabled.
Receive Interrupt Enable. If this bit is set to 1, the receive
interrupt is enabled.
Modem Status Interrupt Enable. If this bit is set to 1, the
modem status interrupt is enabled.
UART Enable. If this bit is set to 1, the UART is enabled.
Data transmission and reception occurs for UART signals.
