8.8 Line Status Register (LSR)
Table 20
Table 20.
When the LSR is read, LSR[4:2] reflect the error bits (BI, FE, PE) of the character at the
top of the RX FIFO (next character to be read). Therefore, errors in a character are
identified by reading the LSR and then reading the RHR.
LSR[7] is set when there is an error anywhere in the RX FIFO, and is cleared only when
there are no more errors remaining in the FIFO.

Line Status Register bits description
Dual UART with I
Description
FIFO data error.
THR and TSR empty. This bit is the Transmit Empty indicator.
THR empty. This bit is the Transmit Holding Register Empty indicator.
Break interrupt.
Framing error.
Parity error.
Overrun error.
Data in receiver.
Rev. 07 — 19 May 2008
logic 0 = no error (normal default condition)
logic 1 = at least one parity error, framing error, or break indication is in
the receiver FIFO. This bit is cleared when no more errors are present
in the FIFO.
logic 0 = transmitter hold and shift registers are not empty
logic 1 = transmitter hold and shift registers are empty
logic 0 = Transmit Hold Register is not empty.
logic 1 = Transmit Hold Register is empty. The host can now load up to
64 characters of data into the THR if the TX FIFO is enabled.
logic 0 = no break condition (normal default condition).
logic 1 = a break condition occurred and associated character is 0x00
(RX was LOW for one character time frame)
logic 0 = no framing error in data being read from RX FIFO (normal
default condition)
logic 1 = framing error occurred in data being read from RX FIFO
(received data did not have a valid stop bit)
logic 0 = no parity error (normal default condition)
logic 1 = parity error in data being read from RX FIFO
logic 0 = no overrun error (normal default condition)
logic 1 = overrun error has occurred
logic 0 = no data in receive FIFO (normal default condition)
logic 1 = at least one character in the RX FIFO
