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:
BANK 0
SOFT_RST - Software-Activated Reset. Active high. Initiated by writing this bit high and terminated by writing the bit low.
The LAN91C110’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 LAN91C110 will
automatically abort a packet being received when the appropriate collision input is 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.
PRMS - Promiscuous mode. When set receives all frames. Does not receive its own transmission unless it is in Full
Duplex!
RX_ABORT - This bit is set if a receive frame was aborted due to length longer than 2K bytes. The frame will not be
received. The bit is cleared by RESET or by the CPU writing it low.
Reserved - Must be 0.
