8.2 Hardware Register Information
The hardware register information can be viewed in Test Mode or used by
programmers wishing to write their own unload and analysis programs. The
table below gives a description of each register numbered 0 to 255. For
multiple byte registers the convention used is – least significant byte to most
significant byte. A byte may contain a number from 0 to 255 (8 bits) and for
calculating multiple byte numbers the first byte is added to the second byte
times 256 plus the third byte times 256 times 256, etc.
eg. The four byte number 1234 would give:
1+(2*256)+(3*256*256)+(4*256*256*256) = 67305985
Arithmetic instructions using 32-bit unsigned integers can represent values
from 0 to 4294967295.
