5 V, 2.2 V and 2.5 V dual UART, 5 Mbit/s (max.), with 64-byte FIFOs
7.5 Line Status Register (LSR)
Table 13 shows the Line Status Register bit settings.
When the LSR is read, LSR[4:2] reflect the error bits (BI, FE, PE) of the character at the
top of the receive FIFO (next character to be read). The LSR[4:2] registers do not
physically exist, as the data read from the receive FIFO is output directly onto the output
data bus, DI[4:2], when the LSR is 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 receive FIFO, and is cleared only
when there are no more errors remaining in the FIFO.
Reading the LSR does not cause an increment of the receive FIFO read pointer. The
receive FIFO read pointer is incremented by reading the RHR.
Table 13.
Line Status Register bits description
Bit
Symbol
Description
7
LSR[7]
FIFO data error.
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.
6
LSR[6]
THR and TSR empty. This bit is the Transmit Empty indicator.
logic 0 = transmitter hold and shift registers are not empty
logic 1 = transmitter hold and shift registers are empty
5
LSR[5]
THR empty. This bit is the Transmit Holding Register Empty indicator.
logic 0 = Transmit Holding Register is not empty
logic 1 = Transmit Holding Register is empty. The processor can now load
up to 64 bytes of data into the THR if the transmit FIFO is enabled.
4
LSR[4]
Break interrupt.
logic 0 = No break condition (normal default condition)
logic 1 = A break condition occurred and associated byte is 00, i.e.,
RXn was LOW for one character time frame
3
LSR[3]
Framing error.
logic 0 = no framing error in data being read from receive FIFO (normal
default condition)
logic 1 = framing error occurred in data being read from receive FIFO, i.e.,
received data did not have a valid stop bit.
2
LSR[2]
Parity error.
logic 0 = no parity error (normal default condition)
logic 1 = parity error in data being read from receive FIFO
1
LSR[1]
Overrun error.
logic 0 = no overrun error (normal default condition)
logic 1 = overrun error has occurred
0
LSR[0]
Data in receiver.
logic 0 = no data in receive FIFO (normal default condition)
logic 1 = at least one character in the receive FIFO
