8.1.26 BIST Control and Status Register 1 (BICSR1)
This register provides the total number of error bytes that was received by the PRBS checker and defines
the Inter packet Gap (IPG) for the packet generator.

DESCRIPTION
0, RO
BIST Error Count:
Holds number of erroneous bytes that were received by the PRBS checker. Value in this
register is locked when write is done to bit[0] or bit[1] (see below).
When PRBS Count Mode set to zero, count stops on 0xFF. See BISCR register (0x0016) for
further details
Note: Writing “1” to bit 15 will lock counter’s value for successive read operation and clear the
BIST Error Counter.
0111 1101, RW BIST IPG Length:
Inter Packet Gap (IPG) Length defines the size of the gap (in bytes) between any 2 successive
packets generated by the BIST. Default value is 0x7D which is equal to 125 bytes
8.1.27 BIST Control and Status Register2 (BICSR2)
This register allows programming the length of the generated packets in bytes for the BIST mechanism.

BIST Packet Length:
Length of the generated BIST packets. The value of this register defines the size (in bytes) of
every packet that generated by the BIST. Default value is 0x5DC which is equal to 1500 bytes

FUNCTION
Cable Diagnostic Process Start:
1 = Start execute cable measurement
0 = Cable Diagnostic is disabled
Diagnostic Start bit is cleared with raise of Diagnostic Done indication.
RESERVED: Writes ignored, read as 0.
Link Quality Indication
00 = Reserved
01 = Good Quality Link Indication
10 = Mid Quality Link Indication
11 = Poor Quality Link Indication
The value of these bits are valid only when link is active – While reading “1” from “Link Status” bit
0 on PHYSTS register (0x0010).
RESERVED: Writes ignored, read as 0.
RESERVED: Writes ignored, read as 0.
Cable Diagnostic Process Done:
1 = Indication that cable measurement process completed
0 = Diagnostic has not completed
Cable Diagnostic Process Fail:
1 = Indication that cable measurement process failed
0 = Diagnostic has not failed
