Transmit BIST Packet Type:
1 = PSR9
0 = User defined packet
Write as 0, ignore on read.
User Defined Packet Content: This field sets the packet content
for the transmit BIST packets if the user defined packet type in bit
10 is selected.
Receive BIST Enable: This bit enables the receive BIST
counter. The BIST counter operation does not interfere with nor-
mal PHY operation.
0 = BIST counter disabled
1 = BIST counter enabled
BIST Counter Select: This bit selects whether the upper or lower
16 bit of the 32 bit counter value are shown in the BIST_CNT reg-
ister.
0 = displays lower 16 bit
1 = displays upper 16 bit
Transmit BIST Packet Count: Sets the number of transmit pack-
ets
000 = continuous transmit
001 = 1 packet
010 = 10 packets
011 = 100 packets
100 = 1,000 packets
101 = 10,000 packets
110 = 100,000 packets
111 = 10,000,000 packets
Write as 0, ignore on read.
Link/Link-ACT Select: This bit has no impact when Reg 0x13.5
= 0.
1 = LINK only
0 = Combined Link/ACT
Expanded Memory Data: Data to be written to or read from ex-
panded memory. Note that in 8-bit mode, the data resides at the
LSB octet of this register.
Expanded Memory Address: Pointer to the address in expand-
ed memory. The pointer is 16-bit wide.
