Transmit operation in mode ‘1’: When the SC16C554/554D 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 if one
or more FIFO locations are empty.
Receive operation in mode ‘1’: When the SC16C554/554D 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. This bit must be a
‘1’ when other FCR bits are written to, or they will not be
programmed.
