11.6.10 UART Modem Status Register
Table 198. UART Line Status Register (U0LSR - address 0x4000 8014, Read Only) bit
The U0MSR is a read-only register that provides status information on the modem input
signals. U0MSR[3:0] is cleared on U0MSR read. Note that modem signals have no direct
effect on the UART operation. They facilitate the software implementation of modem
signal operations.

When the stop bit of a received character is a logic 0, a framing
error occurs. A U0LSR read clears U0LSR[3]. The time of the
framing error detection is dependent on U0FCR0. Upon detection
of a framing error, the RX will attempt to re-synchronize to the
data and assume that the bad stop bit is actually an early start bit.
However, it cannot be assumed that the next received byte will be
correct even if there is no Framing Error.
Note: A framing error is associated with the character at the top
of the UART RBR FIFO.
Framing error status is inactive.
Framing error status is active.
When RXD1 is held in the spacing state (all zeros) for one full
character transmission (start, data, parity, stop), a break interrupt
occurs. Once the break condition has been detected, the receiver
goes idle until RXD1 goes to marking state (all ones). A U0LSR
read clears this status bit. The time of break detection is
dependent on U0FCR[0].
Note: The break interrupt is associated with the character at the
top of the UART RBR FIFO.
Break interrupt status is inactive.
Break interrupt status is active.
THRE is set immediately upon detection of an empty UART THR
and is cleared on a U0THR write.
U0THR contains valid data.
U0THR is empty.
TEMT is set when both U0THR and U0TSR are empty; TEMT is
cleared when either the U0TSR or the U0THR contain valid data.
U0THR and/or the U0TSR contains valid data.
U0THR and the U0TSR are empty.
U0LSR[7] is set when a character with a RX error such as framing
error, parity error or break interrupt, is loaded into the U0RBR.
This bit is cleared when the U0LSR register is read and there are
no subsequent errors in the UART FIFO.
U0RBR contains no UART RX errors or U0FCR[0]=0.
UART RBR contains at least one UART RX error.
