Roger, I have another question for
you if you don't mind.

Since the 68HC908GP32 has only 32K flash
internal memory how is the 53K  MSN Extra code
accommodated?

Paul,

Memory map is located here:
http://www.megasquirt.info/v22manual/mcode.htm#memmap

Each row in the .s19 file represents only 16 bytes of
program data, in hex form.  The first 8 characters are
data type, and destination address.  The last two
characters are checksum for that 16-byte chunk.

Roger.

OK my mistake. I forgot that fact. Thanks.
So the code size is only 16/26 times 13 K or 8K for the
basic code and 32K for the extra code. Does that sound
about right. Here is the memory map from the Motorola
68HC908GP32 CPU pdf.
