SC16C750B
5 V, 3.3 V and 2.5 V UART with 64-byte FIFOs
FCR[3]
(continued)
Transmit operation in mode ‘1’: When the SC16C750B is in FIFO mode
(FCR[0] = logic 1; FCR[3] = logic 1), the TXRDY pin will be a logic 1 when
the transmit FIFO is completely full. It will be a logic 0 when the FIFO is
emptied.
Receive operation in mode ‘1’: When the SC16C750B is in FIFO mode
(FCR[0] = logic 1; FCR[3] = logic 1) and the trigger level has been reached,
or a Receive Time-Out has occurred, the RXRDY pin will go to a logic 0.
Once activated, it will go to a logic 1 after there are no more characters in
the FIFO.
2
FCR[2]
XMIT FIFO reset.
logic 0 = no FIFO transmit reset (normal default condition)
logic 1 = clears the contents of the transmit FIFO and resets the FIFO
counter logic (the transmit shift register is not cleared or altered). This bit
will return to a logic 0 after clearing the FIFO.
1
FCR[1]
RCVR FIFO reset.
logic 0 = no FIFO receive reset (normal default condition)
logic 1 = clears the contents of the receive FIFO and resets the FIFO
counter logic (the receive shift register is not cleared or altered). This bit
will return to a logic 0 after clearing the FIFO.
0
FCR[0]
FIFO enable.
logic 0 = disable the transmit and receive FIFO (normal default condition)
logic 1 = enable the transmit and receive FIFO
