Hexmate
5.16.1.3 -ADDRESSING
By default, all address parameters in hexmate options expect that values will be entered as byte
addresses. In some device architectures the native addressing format may be something other than
byte addressing. In these cases it would be much simpler to be able to enter address-components
in the device’s native format. To facilitate this, the -ADDRESSING option is used. This option takes
exactly one parameter which configures the number of bytes contained per address location. If for
example a device’s program memory naturally used a 16-bit (2 byte) word-addressing format, the
option -ADDRESSING=2 will configure hexmate to interpret all command line address fields as word
addresses. The affect of this setting is global and all hexmate options will now interpret addresses
according to this setting. This option will allow specification of addressing modes from one byte-
per-address to four bytes-per-address.
5.16.1.4 -BREAK
This option takes a comma separated list of addresses. If any of these addresses are encountered
in the hex file, the current data record will conclude and a new data record will recommence from
the nominated address. This can be useful to use new data records to force a distinction between
functionally different areas of program space. Some hex file readers depend on this.
5.16.1.5 -CK
The -CK option is for calculating a checksum. The usage of this option is:
where:
150
-CK=start-end@destination[+offset][wWidth][tCode][gAlogithm]
Start and End specify the address range that the checksum will be calculated over.
Destination is the address where to store the checksum result. This value cannot be within the
range of calculation.
Offset is an optional initial value to add to the checksum result. Width is optional and specifies
the byte-width of the checksum result. Results can be calculated for byte-widths of 1 to 4
bytes. If a positive width is requested, the result will be stored in big-endian byte order. A
negative width will cause the result to be stored in little-endian byte order. If the width is left
unspecified, the result will be 2 bytes wide and stored in little-endian byte order.
Code is a hexadecimal code that will trail each byte in the checksum result. This can allow
each byte of the checksum result to be embedded within an instruction.
