MC68EN302 REFERENCE MANUAL
4-11
DRTY—Disable Retry.
0 = The MC68EN302 performs retry error reporting normally.
1 = The MC68EN302 does not perform any retries of a frame before reporting a retry
error in the transmit descriptor for the frame.
RWS—Receive Watchdog Timer Short.
0 = The Receive Watchdog Timer operates normally
1= The Receive Watchdog Timer is short cycled for test purpose causing the Receive
Watchdog Timer to expire, and a BABR interrupt to be generated if more than 100
bytes in a frame are received.
TWS—Transmit Watchdog Timer Short.
0 = The Transmit Watchdog Timer operates normally.
1 = The Transmit Watchdog Timer is short cycled for test purposes causing the
Transmit Watchdog Timer to expire and a BABT interrupt to be generated if more
than 100 bytes in a frame are transmitted.
4.1.9 AR CONTROL REGISTER (AR_CNTRL)
The AR Control register controls AR memory operation and can be written only when the
ETHER_EN bit in the Control register is clear. Bits in this register are not changed if the
ETHER_EN bit in the Control register is set. This register is set to the value $0000 on a
reset.
HASH_EN—Hash mode enable.
0 = Perfect-entry match mode is selected for all entries
1= Hash mode is enabled instead of perfect matches on entries 62 and 63.
INDEX_EN—Index enable.
0 = The receive buffer data pointer is unmodified
1= Pass either line number or hash index into the upper byte of the receive buffer
descriptor’s data pointer.
MULT1–MULT0—Multicast and broadcast reception control.
MULT controls whether multicast frames are received. Broadcast is the special multicast
address of all ones.
