Refer to
Table 75
for bit assignments.
Repeater Serial Configuration
Register
R
13B
This register holds user-defined data. These bits may
be used to indicate the type of board configuration, port
count or other vendor-related data. Default is set by
pins. Refer to
Table 76
for bit assignments.
Device/Revision ID register
R
13C
This register follows the IEEE 1149.1 specification.
Refer to
Table 77
for bit assignments.
The upper 4 bits identify the device revision level. The
next 16 bits store the Part ID Number. The next 11 bits
contain a JEDEC Manufacturer ID, which for Intel is
hexadecimal
‘
FE
’
. The lowest bit (0) is set only for the
first device in a chain. The encoding scheme used for
the Product ID field is implementation dependent.
