Description

0x0E28

[7:0]

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 specified

by the next two bytes. The controller stores 0x63 in the EEPROM and increments the EEPROM address

pointer.

0x0E29

[7:0]

Profile 4

and

Profile 5

The default value of these two registers is 0x0700. Note that Register 0x0E29 and Register 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 in the EEPROM and increments the EEPROM pointer by 2. It then transfers 100 bytes from the

101 (100 data bytes and one checksum byte). The 99 bytes transferred correspond to 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, which tells the controller to transfer 100 bytes of data (99 + 1) beginning at the address

specified by the next two bytes. The controller stores 0x63 in the EEPROM and increments the EEPROM

address pointer.

0x0E2C

[7:0]

Profile 6

and

Profile 7

The default value of these two registers is 0x0780. Note that Register 0x0E2C and Register 0x0E2C 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 in the 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 correspond to the Profile 6 and Profile 7 parameters in the

I/O

update

The default value of this register is 0x80, which the controller interprets as an I/O update instruction. The

controller stores 0x80 in the EEPROM and increments the EEPROM address pointer.

Operational

controls

The default value of this register is 0x10, which the controller interprets as a data instruction. Its decimal

value is 16, which tells the controller to transfer 17 bytes of data (16 + 1) beginning at the address

specified by the next two bytes. The controller stores 0x10 in the EEPROM and increments the EEPROM

address pointer.

0x0E30

[7:0]

Operational

controls

The default value of these two registers is 0x0A00. Note that Register 0x0E30 and Register 0x0E31 are the

most significant and least significant bytes of the target address, respectively. Because the previous

The controller stores 0x0A00 in the EEPROM and increments the EEPROM pointer by 2. It then transfers

17 bytes from the register map (beginning at Address 0x0A00) to the EEPROM and increments the

EEPROM address pointer by 18 (17 data bytes and one checksum byte). The 17 bytes transferred

correspond to the operational controls 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. The

controller stores 0x80 in the EEPROM and increments the EEPROM address pointer.
