PRELIMINARY
status bit. Transmission stops and EPH INT is set if STP_SQET is in the TCR is also set when SQET is
set. This bit is cleared by setting TXENA high.
16COL - 16 collisions reached. Set when 16 collisions are detected for a transmit frame. TXENA bit in
TCR is reset. Cleared when TXENA is set high.
LTX_MULT - Last transmit frame was a multicast. Set if frame was a multicast. Cleared at the start of
every transmit frame.
MULCOL - Multiple collision detected for the last transmit frame. Set when more than one collision was
experienced. Cleared when TX_SUC is high at the end of the packet being sent.
SNGLCOL - Single collision detected for the last transmit frame. Set when a collision is detected. Cleared
when TX_SUC is high at the end of the packet being sent.
TX_SUC - Last transmit was successful. Set if transmit completes without a fatal error. This bit is cleared
by the start of a new frame transmission or when TXENA is set high. Fatal errors are:
16 collisions (1/2 duplex mode only)
SQET fail and STP_SQET = 1 (1/2 duplex mode only)
FIFO Underrun
Carrier lost and MON_CSN = 1 (1/2 duplex mode only)
Late collision (1/2 duplex mode only)

SOFT_RST - Software-Activated Reset. Active high. Initiated by writing this bit high and terminated by
writing the bit low. The LAN91C100FD’s configuration is not preserved except for Configuration, Base, and
IA0-IA5 Registers. EEPROM is not reloaded after software reset.
FILT_CAR - Filter Carrier. When set filters leading edge of carrier sense for 12 bit times (3 nibble times).
Otherwise recognizes a receive frame as soon as carrier sense is active. (Does NOT filter RX DV on MII!)
ABORT_ENB - Enables abort of receive when collision occurs. Defaults low. When set, the
LAN91C100FD will automatically abort a packet being received when the appropriate collision input is
activated (COL100 for MII, COL for non-MII). This bit has no effect if the SWFDUP bit in the TCR is set.
STRIP_CRC - When set it strips the CRC on received frames. When clear the CRC is stored in memory
following the packet. Defaults low.
RXEN - Enables the receiver when set. If cleared, completes receiving current frame and then goes idle.
Defaults low on reset.
ALMUL - When set accepts all multicast frames (frames in which the first bit of DA is '1'). When clear
accepts only the multicast frames that match the multicast table setting. Defaults low.
