Description

0E25

[7:0]

Profile 2 and Profile 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 specified by the next two bytes. The controller

stores 0x63 in the EEPROM and increments the EEPROM address pointer.

0E26

[7:0]

Profile 2 and Profile 3

The default value of these two registers is 0x0680. Note that Register 0E26 and

address, respectively. Because the previous register contains a data instruction,

these two registers define a starting address (in this case, 0x0680). The controller

stores 0x0680 in the 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 increments the EEPROM address pointer by 101 (100 data bytes and

one checksum byte). The 99 bytes transferred correspond to the Profile 2 and

Profile 3 parameters in the 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 this 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.

0E29

[7:0]

Profile 4 and Profile 5

The default value of these two registers is 0x0700. Note that Register 0E29 and

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 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 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 this 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.

0E2C

[7:0]

Profile 6 and Profile 7

The default value of these two registers is 0x0780. Note that Register 0E2C and

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 register map.

0E2D

[7:0]

0E2E

[7:0]

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.
