4.12 UART1 Modem Status Register (U1MSR - 0xE001 0018)
Table 408. UART1 Line Status Register (U1LSR - address 0xE001 0014, Read Only) bit
The U1MSR is a read-only register that provides status information on the modem input
signals. U1MSR[3:0] is cleared on U1MSR read. Note that modem signals have no direct
affect on UART1 operation, they facilitate software implementation of modem signal
operations.

Set upon low to high transition of input RI. Cleared on an U1MSR
read.
No change detected on modem input, RI.
Low-to-high transition detected on RI.
Set upon state change of input DCD. Cleared on an U1MSR read.
No change detected on modem input, DCD.

Clear To Send State. Complement of input signal CTS. This bit is
connected to U1MCR[1] in modem loopback mode.
Rev. 04 — 26 August 2009
THRE is set immediately upon detection of an empty UART1
THR and is cleared on a U1THR write.
U1THR contains valid data.
U1THR is empty.
TEMT is set when both U1THR and U1TSR are empty; TEMT is
cleared when either the U1TSR or the U1THR contain valid data.
U1THR and/or the U1TSR contains valid data.
U1THR and the U1TSR are empty.
U1LSR[7] is set when a character with a RX error such as framing
error, parity error or break interrupt, is loaded into the U1RBR.
This bit is cleared when the U1LSR register is read and there are
no subsequent errors in the UART1 FIFO.
U1RBR contains no UART1 RX errors or U1FCR[0]=0.
UART1 RBR contains at least one UART1 RX error.
