7.2.2 Zone1: Local Configuration Registers
The Zone1 region of EEPROM contains the program value
of the vendor-specific Local Configuration Registers using
one or more configuration WORDs. Registers are selected
using a 7-bit byte-offset field. This offset value is the offset
from Base Address Registers in I/O or memory space (see
section 4.4).
Note: Not all of the registers in the Local Configuration Register set are
writable by EEPROM. If bit3 of the header is set, Zone1
configuration WORDs follow the header declaration. The
format of configuration WORDs for the Local Configuration
Registers in Zone1 are described in Table 9.

Bits Description
15 ‘0’ = There are no more Configuration WORDs
to follow in Zone1. Move to the next available
zone or end EEPROM program if no more zones
are enabled in the Header.
‘1’ = There is another Configuration WORD to
follow for the Local Configuration Registers.
14:8 These seven bits define the byte-offset of the
Local configuration register to be programmed.
For example the byte-offset for LT2[23:16] is
0x0E.
7:0 8-bit value of the register to be programmed
