Description
The default value of this register is 0x19, which the controller interprets as a data
instruction. Its decimal value is 25, which tells the controller to transfer 26 bytes of
data (25 + 1) beginning at the address specified by the next two bytes. The
controller stores 0x19 in the EEPROM and increments the EEPROM address pointer.
The default value of these two registers is 0x0400. Note that Register 0E1C and
Register 0E1D 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, 0x0400). The controller
stores 0x0400 in the EEPROM and increments the EEPROM pointer by 2. It then
transfers
26 bytes from the register map (beginning at Address 0x0400) to the EEPROM and
increments the EEPROM address pointer by 27 (26 data bytes and one checksum
byte). The 26 bytes transferred correspond to the clock distribution parameters in
the register map.
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.
Description
The default value of this register is 0x07, which the controller interprets as a data
instruction. Its decimal value is 7, which tells the controller to transfer eight bytes
of data (7 + 1) beginning at the address specified by the next two bytes. The
controller stores 0x07 in the EEPROM and increments the EEPROM address pointer.
The default value of these two registers is 0x0500. Note that Register 0E20 and
Register 0E21 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, 0x0500). The controller
stores 0x0500 in the EEPROM and increments the EEPROM pointer by 2. It then
transfers eight bytes from the register map (beginning at Address 0x0500) to the
EEPROM and increments the EEPROM address pointer by nine (eight data bytes
and one checksum byte). The eight bytes transferred correspond to the reference
inputs parameters in the register map.
Description
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.
The default value of these two registers is 0x0600. Note that Register 0E23 and
Register 0E24 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, 0x0600). The controller
stores 0x0600 in the EEPROM and increments the EEPROM pointer by 2. It then
transfers 100 bytes from the register map (beginning at Address 0x0600) to the
EEPROM and increments the EEPROM address pointer by 101 (100 data bytes and
Profile 1 parameters in the register map.
one checksum byte). The 99 bytes transferred correspond to the Profile 0 and
