EE_ADDR
EE_ADDR is a static register used to store the internal
EEPROM address to read or write using commands
0x13 and 0x14 respectively. Eight user-accessible
bytes in the EEPROM are available.
Address
0x00 – 0x03
0x04 – 0x3B
0x3C – 0x3F
0x40 – 0xFF

EE_STAT
EE_STAT is a dynamic register which indicates the
validity of the data read from the internal EEPROM.
After an EEPROM read command (0x13), the value of
the EE_STAT register indicates the validity of the data
in the EE_DATA register.

Description
No error, EE_DATA valid
Single-bit error corrected, EE_DATA valid
Double-bit error, EE_DATA invalid
Reserved
See Device Serial Number and User Data on page 64
for more information.
Do not write to EE_ADDR while the EEPROM is be-
ing accessed (commands 0x11, 0x14, or 0x17) or the
EEPROM may be corrupted.

EE_DATA
EE_DATA is a dynamic register used to store the data
read from or written to the internal EEPROM using com-
mands 0x13 and 0x14 respectively. See Device Serial
Number and User Data on page 64 for more informa-
tion.
