which
calculates a hash from
start to
end addresses, placing the result at
destination, and the specifications are as
follows:
width=n selects the width of the
hash result in bytes. A negative width will store the result in
little-endian byte order.offset=nnnn specifies an initial
value or offset to be added to the hash.algorithm=n selects the hash
algorithm to use.code=nn.Base is a
hexadecimal code that will trail each byte in the hash result. This can
allow each byte of the hash result to be embedded within an
instruction.polynomial=nn hexadecimal value
which is the polynomial to be used for CRC hashes.revword=n reads the data in reserve
order with the word width specified.skip=n.Bytes skips
the MSB in the word width specified.xor=n is a hexadecimal value that
will be XORed with the hash result before it stored.

MPLAB® XC8 C Compiler User’s Guide for
PIC® MCU for full information regarding this
option. Note that this field does not map to any compiler option, but will instead
trigger a post-build execution of the Hexmate utility.
