Transmit operation in mode ‘1’:
When the SC16C2552 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 SC16C2552 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
signal at the MF 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.
NOTE: The AFR register must be set to the RXRDY mode prior to
any possible reading of the RXRDY signal.
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.
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.
FIFOs enabled.
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.
