Description
0x0E25
[7:0]
Profile2 andProfile 3
The default value of this register is 0x63, which the controller interprets as a data instruction. Its
decimal value is 99, which tells the controller to transfer 100 bytes of data (99 + 1), beginning at
the address specifiedby the next two bytes. The controller stores 0x63 in the EEPROM and
increments the EEPROM address pointer.
0x0E26
[7:0]
Profile2 andProfile 3
The default value of these two registers is 0x0680. Note that Register(0x0E26 andRegister0x0E27
are the most significant and least significant bytes of the target address, respectively. Because
the previous register contains a data instruction, these two registers define a starting address
(in this case, 0x0680). The controller stores 0x0680inthe EEPROM and increments the EEPROM
pointer by 2. It then transfers 100 bytes from the register map (beginning at Address 0x0680) to
the EEPROM and incrementsthe EEPROM address pointer by 101 (100data bytes andone checksum
byte). The 99 bytes transferred correspondto the Profile 2 and Profile 3 parameters inthe
register map.

Profile 4 and Profile 5
The default value of this register is 0x63, which the controller interprets as a data instruction.
Its decimal value is 99, which tells the controller to transfer 100 bytes of data (99 + 1)
beginning at the address specifiedby the next two bytes. The controller stores 0x63 in the
EEPROM and increments the EEPROM address pointer.
0x0E29

Profile 4 and Profile 5
The default value of these two registers is 0x0700. Note that Register
0x0E29andRegister 0x0E2A
are the most significant and least significant bytes of the target address, respectively. Because
the previous register contains a data instruction, these two registers define a starting address
(in this case, 0x0700). The controller stores 0x0700 inthe EEPROM and increments the EEPROM
pointer by 2. It then transfers 100 bytes from the register map (beginning at Address 0x0700)
to the EEPROM and increments the EEPROM address pointer by 101 (100 data bytes and one
checksum byte). The 99 bytes transferred correspondto the Profile 4 and Profile 5 parameters
in the register map.

Profile 6 and Profile 7
The default value of this register is 0x63, which the controller interprets as a data instruction.
Its decimal value is 99, this tells the controller to transfer 100 bytes of data (99 + 1) beginning
at the address specifiedby the next two bytes. The controller stores 0x63 in the EEPROM and
increments the EEPROM address pointer.

Profile 6 and Profile 7
The default value of these two registers is 0x0780. Note that Register0x0E2CandRegister 0x0E2D
are the most significant and least significant bytes of the target address, respectively. Because
the previous register contains a data instruction, these two registers define a starting address
(in this case, 0x0780). The controller stores 0x0780 inthe EEPROM and increments the EEPROM
pointer by 2. It then transfers 100 bytes from the register map (beginning at Address 0x0780)
to the EEPROM and increments the EEPROM address pointer by 101 (100 data bytes and one
checksum byte). The 99 bytes transferred correspondto the Profile 6 and Profile 7 parameters
in the register map.

I/O update
The default value of this register is 0x80, which the controller interprets as an I/O update
instruction. Thecontrollerstores 0x80inthe EEPROM andincrements the EEPROM address pointer.
