Eeprom bit definitions
Following table gives the bit definitions for all addresses that can be modified by the user. All other
addresses contain specific calibration data and should be left unchanged.
Note that some bits marked “RES” are reserved and should never not be changed by the user. If other
bits in such an address must be changed, read original contents first to get the status of the reserved bits.
EEPROM BIT DEFENITIONS
Eeprom Hamming coding
All addresses in the eeprom are coded using hamming code. Therefore, if one wants to program data into
any eeprom address, the hamming bits must be calculated first. This is not done by the
There are 11 bits + 4 hamming bits + 1 extra redundant bit in the eeprom. Data bits are numbered
D10..D0, Hamming H4..H1, the extra bit is called K.
The bit definitions in the eeprom words are:
The hamming bits are calculated as follows:
