DATA2 - Non-Volatile Memory Data Register Byte 2
DATA1 - Non-Volatile Memory Data Register 1
DATA0 - Non-Volatile Memory Data Register 0
CMD - Non-Volatile Memory Command Register
The DATA2, DATA1 and ADDR0 registers represents the 24-bit value DATA.
• Bit 7:0 - DATA[23:16]: NVM Data Register 2
This register gives the data value byte 2 when running CRC check on application section, boot
section or combined.
• Bit 7:0 - DATA[15:8]: NVM Data Register Byte 1
This register gives the data value byte 1 when accessing application and boot section.
• Bit 7:0 - DATA[7:0]: NVM Data Register Byte 0
This register gives the data value byte 0 when accessing either of the memory locations.
• Bit 7 - Reserved
This bit is unused and reserved for future use. For compatibility with future devices, always write
this bit to zero when this register is written.
• Bit 6:0 -CMD[6:0]: NVM Command
These bits define the programming commands for the flash. Bit six is set for external program-
ming commands. See "Memory Programming data sheet" for programming commands.
