Reserved. Unknown During Read.
Loopback Enable, for SIR and UART only.
1 - If the SIR Enable bit is also set to “1”, and register
UART2TMR bit 1 (SIRTEST) is set to “1”, the SIR output
path is inverted and fed through to the SIR input path. The
SIRTEST bit in the test register must be set to “1” to
override the normal half-duplex SIR operation. This should
be the requirement for accessing the test registers during
normal operation, and SIRTEST must be cleared to “0”
when loopback testing is finished. This feature reduces the
amount of external coupling required during system test.
0 - 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.
