DESCRIPTION
Output. Chip Select provided for mapping of PHY
functions into LAN91C100FD decoded space.
Active on accesses to LAN91C100FD’s eight lower
addresses when the BANK SELECTED is 7.
Input. Used to discard the receive packet being
stored in memory. Assertion of the pin during a
packet reception results in the interruption of
packet reception into memory. The memory
allocated to the packet and the packet number in
use are freed. The input is driven asynchronously
and
is
synchronized
LAN91C100FD. Pin assertion may take place at
any time during the receive DMA packet. The
assertion has no effect if there is no packet being
DMAed to memory or if asserted during the last
DMA write to memory. Works for both MII and
ENDEC. The typical use of nRXDISC is with the
LAN91C100FD in PRMS mode with an external
associative memory use for address filtering.
*Note: The pin must be asserted for a minimum
of 80ns.
Output. Active when the first dword of the address
is written (RCVDMA=1, RA10-RA4=0, RA3-
RA2=X).
