Receive Direct Frame-Available Output. RXFA_i (i = 0, 1, 2, 3) is the
active-high output signal indicating the status of receive FIFO #i.
RXFA_i (i = 0, 1, 2, 3) outputs are always driven.
ATM-UTOPIA Mode
RXFA_i (i = 0, 1, 2, 3) is used to perform cell-level handshake on receive
FIFO #i and goes high when receive FIFO #i contains one or more
complete ATM cells.
When the ATM cell being read in the UTOPIA interface is the last
complete cell in FIFO #i, RXFA_i (i = 0, 1, 2, 3) is deasserted on the next
RXCLK_i rising edge, after the word output in the RXDATA_i bus
contains the payload byte (1, 2, … 48) indicated by RcvCADeassert[5:0]
(register R_UICHCNF). Configuring RcvCADeassert[5:0] to an
appropriate value, ensures that the ATM Layer device can detect that the
current ATM cell is the last cell in the FIFO, four clock cycles (or more)
before reading the last word.
POS-UTOPIA Mode
RXFA_i (i = 0, 1, 2, 3) indicates the availability of data in FIFO #i.
RXFA_i is asserted when the receive FIFO #i contains an end-of-packet
or contains a number of 32-bit words equal to or greater than the
“receive programmable watermark” (channel register R_PWM).
RXFA_i (i = 0, 1, 2, 3) is deasserted when the receive FIFO #i does not
contain an end of packet and contains a number of 32-bit words smaller
than the “receive programmable watermark” (channel register R_PWM).
RXFA_i (i = 0, 1, 2, 3) is updated on the rising edge of RXCLK_i.
