Data Sheet
SAVING REGISTER SETTINGS TO THE EEPROM
The register settings cannot be saved to the factory default set-
tings located in Page 0 of the EEPROM main block. This is to
prevent the user from accidentally overriding the factory trim
ADP1046
EEPROM CRC CHECKSUM
As a simple method of checking that the values downloaded
from the EEPROM are consistent with the internal registers,
a CRC checksum is implemented.
settings and default register settings.
Save Register Settings to User Settings
The register settings can be saved to the user settings located in
Page 1 of the EEPROM main block using the STORE_USER_ALL
command (Register 0x82). Before this command can be executed,
the EEPROM must first be unlocked for writing (see the Unlock
After the register settings are saved to the user settings, any
subsequent power cycle automatically downloads the latest
stored user information from the EEPROM into the internal
?
?
When the data from the internal registers is saved to the
EEPROM (Page 1 of the main block), the total number
of 1s from all the registers is counted and written into the
EEPROM as the last byte of information. This is called
the CRC checksum.
When the data is downloaded from the EEPROM into the
internal registers, a similar counter that sums all 1s from
the values loaded into the registers is saved. This value is
compared with the CRC checksum from the previous
upload operation.
registers.
Note that execution of the STORE_USER_ALL command auto-
matically performs a page erase to Page 1 of the EEPROM main
block, after which the register settings are stored in the EEPROM.
Therefore, it is important to wait at least 40 ms for the operation
to complete before executing the next I 2 C command.
If the values match, the download operation was successful. If
the values differ, the EEPROM download operation failed, and
the EEPROM CRC fault flag is set (Bit 1 of Register 0x03).
To read the EEPROM CRC checksum value, execute the
EEPROM_CRC_CHKSUM command (Register 0x84).
This command returns the CRC checksum accumulated in
the counter during the download operation.
Note that the CRC checksum is an 8-bit cyclical accumulator
that wraps around to 0 when 255 is reached.
