The programmer should be able to read data memory
information from a hex file and conversely (as an
option), write data memory contents to a hex file along
with program memory information and Configuration
Word
information.
The physical address range of the 256 data memory is
0x0000-0x00FF. However, these
logically mapped to address 0x2100-0x21FF for use in
writing assembly code. This provides a way of
differentiating between the data and program memory
locations in this range. The format for data memory
storage is one data byte per address location, LSb
aligned. A simple example of data memory is given
below:

SUM[a:b] = [Sum of locations a to b inclusive]
SUM_ID = User ID locations masked by 0xF then made into a 16-bit value with ID0 as the Most Significant
nibble.
*Checksum = [Sum of all the individual expressions] MODULO [0xFFFF]
+ = Addition
& = Bitwise AND

CONTENTS IN HEX FILE
For example, ID0 = 0x1, ID1 = 0x2, ID3 = 0x3, ID4 = 0x4, then SUM_ID = 0x1234.
The 4 LSbs of the unprotected checksum is used for the example calculations.
