Hexmate
5.15.1.10 -FORMAT
The -FORMAT option can be used to specify a particular variant of INHX format or adjust maximum
record length. The usage of this option is:
where:
The possible types that are supported by this option are listed in Table 5.11. Note that INHX032 is
not an actual INHX format. Selection of this type generates an INHX32 file but will also initialize
the upper address information to zero. This is a requirement of some device programmers.

Code is a little endian hexadecimal code to replace the sequences that match the -FIND crite-
ria.
Mask is an optional bit mask to specify which bits within Code will replace the code sequence
that has been matched. This may be useful if, for example, it is only necessary to modify 4
bits within a 16-bit instruction. The remaining 12 bits can masked and be left unchanged.
-FORMAT=Type[,Length]
Type specifies a particular INHX format to generate.
Length is optional and sets the maximum number of bytes per data record. A valid length is
between 1 and 16, with 16 being the default.

Consider this case. A bootloader trying to download an INHX32 file fails succeed
because it cannot process the extended address records which are part of the INHX32
standard. You know that this bootloader can only program data addressed within the
range 0 to 64k, and that any data in the hex file outside of this range can be safely
disregarded. In this case, by generating the hex file in INHX8M format the operation
might succeed. The hexmate option to do this would be -FORMAT=INHX8M.
Now consider this. What if the same bootloader also required every data record to
contain eight bytes of data, no more, no less? This is possible by combining -FORMAT
with -FILL. Appropriate use of -FILL can ensure that there are no gaps in the data
for the address range being programmed. This will satisfy the minimum data length
requirement. To set the maximum length of data records to eight bytes, just modify the
previous option to become -FORMAT=INHX8M,8.
