The s-record file can now be edited to modify the LSM/DPM configuration. The s-record file format
S2xxyyyyyyzzzzcs is as follows:
•
S2
Single-character start code S followed by a single-character record type. S2 indicates the line is a
data sequence with 3 bytes of address.
•
xx
Two hexadecimal digits indicating the byte count in hexadecimal (a data + checksum).
•
yyyyyy
Six hexadecimal digits to indicate the three bytes of address that specify the memory location of
the first data byte
•
zzzz
Zero to sixty-four pairs of hexadecimal characters specifying the data bytes
•
cs
Two hex digits indicating the checksum, which is calculated by taking the sum of the all the bytes
