A.1 Intel-Hex Object Format
The Intel-hex object format supports 16-bit addresses and consists of a
nine-character (four field) prefix that defines the start of record, byte count,
load address, record type, and a two character sumcheck suffix.
The two record types, which are represented in the nine-character prefix, are
described below:
00 = Data record (begins with the colon start character)
01 = End-of-file record
Record type 00, the data record, begins with the colon (:) start character and
is followed by the byte count, the address of the first data byte, the record type
(00), and the sumcheck. The sumcheck is the 2s complement (in binary) of the
preceding bytes in the record, including the byte count, address, and data
bytes.
Record type 01, the end-of-file record, also begins with the colon (:) start
character. The colon is followed by the byte count, address, record type (01),
and sumcheck.
