DATA1 – Data Register 1
DATA2 – Data Register Byte 2
CMD – Command Register
CTRLA – Control Register A
• Bit 7:0 – DATA[15:8]: Data Register Byte 1
This register gives the data value byte 1 when accessing NVM locations.
• Bit 7:0 – DATA[23:16]: Data Register 2
This register gives the data value byte 2 when accessing NVM 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]: Command
These bits define the programming commands for the flash. Bit 6 is only set for external pro-
gramming commands. See
• Bit 7:1 – Reserved
These bits are unused and reserved for future use. For compatibility with future devices, always
write these bits to zero when this register is written.
