12.6.2.1 Write Data Command
The Write Data Command is used to write a list of given 1, 2 or 4-byte values or bitmasks
to a corresponding list of target addresses. The format of Write Data Command, again a big
endian byte array, is shown in the
where:
964
Tag
• Tag: A single byte field set to 0xCC
• Length:
• Address: Target address to which the data should be written
• Value/Mask: Data value or bit mask to be written to the preceding address
A two byte field in big endian format containing the length of the Write Data Command,
in bytes, including the header.
