" Language:	Motorola S-Record
" Maintainer:	Markus Heidelberg <markus.heidelberg@web.de>
" Last Change:	2015 Feb 24

" Each record (line) is built as follows:
"
"    field       digits          states
"
"  +----------+
"  | start    |  1 ('S')         srecRecStart
"  +----------+
"  | type     |  1               srecRecType, (srecRecTypeUnknown)
"  +----------+
"  | count    |  2               srecByteCount
"  +----------+
"  | address  |  4/6/8           srecNoAddress, srecDataAddress, srecRecCount, srecStartAddress, (srecAddressFieldUnknown)
"  +----------+
"  | data     |  0..504/502/500  srecDataOdd, srecDataEven, (srecDataUnexpected)
"  +----------+
"  | checksum |  2               srecChecksum
"  +----------+
"
" States in parentheses in the upper format description indicate that they
" should not appear in a valid file.

" For version 5.x: Clear all syntax items
" For version 6.x: Quit when a syntax file was already loaded
