Address Register 0
The ADDR0, ADDR1, and ADDR2 registers represent the 24-bit value ADDR. This is used for
addressing all NVM sections for read, write, and CRC operations.
• Bit 7:0 – ADDR[7:0]: Register Byte 0
This register gives the address low byte when accessing NVM locations.
• Bit 7:0 – ADDR[15:8]: Address Register Byte 1
This register gives the address high byte when accessing NVM locations.
• Bit 7:0 – ADDR[23:16]: Address Register Byte 2
This register gives the address extended byte when accessing NVM locations.
The DATA0, DATA1, and DATA registers represent the 24-bit value DATA. This holds data dur-
ing NVM read, write, and CRC access.
• Bit 7:0 – DATA[7:0]: Data Register Byte 0
This register gives the data value byte 0 when accessing NVM locations.
