Where can I find the address in the code?

[Dany]

0x0000 0xF030EFC0 GOTO 24960

Above is an extract of a list file of the reset vector of a P18F2550 program. The hex value of 24960 is $6180, but I do not see $61 nor $80 in the opcodes.

According the datasheet they should be visible.

Can anyone help me?

Thanks in advance.

Hi Dany,

Assembly instructions consist of 16-bit words (one or more) in PIC18s so program memory is addressed in words within assembly instruction, i.e. twice smaller than in bytes. In your case, the address $6180 is coded as $30C0 in the GOTO instruction (F030EFC0). You've worked too long with bigger processors, apparently .

Thanks very much Janni! Problem solved...
