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.
