/*
When printing a line from the pipe, it could look like this:
01:8006 f4 fb 86 iwt r4, #$86fb
The values are:
program bank : 01
adress : 8006
values at memory address 8006 : f4 fb 86
instruction in the pipe : iwt r4, #$86fb
Note! If the instruction has more than one byte (like in 'iwt') and the instruction is in a delay slot,
the second and third byte displayed will not be the same as those used.
Since the instrction is in a delay slot,
the first byte of the instruction will be taken from the pipe at the address after the branch instruction,
and the next one or two bytes will be taken from the address that the branch points to.
This is a bit complicated, but I've taken this into account, in this debug function.
(See the diffrence of how the values vPipe1 and vPipe2 are read, compared to the values vByte1 and vByte2)
