Hi Everyone,

I'm trying to understand what the CPI command does with the C flag.

C: Rd7 •K7 +K7 •R7+ R7 •Rd7

Set if the absolute value of K is larger than the absolute value of Rd; cleared otherwise.

The first Rd7 has a line above it and the last Rd7 has a line above it.

Q1 - Why does it say "absolute" value?

Q2 - It does even look at bits 6-0, how does this work?

Q3 - What does the line mean? NOT?

Q4 - The dot means AND, right?

Q5 - The plus means ADD, right?

A circle with a plus in it means exclusive or.

Or has a lowercase v for some reason.

Equal is an arrow.

Q6 - In the TST command it says the S flag is N ^ V (^ used for exclusive or). Does it mean the N and V flags? V is always 0. What is the point of this. Won't S always be just plain N?

Thanks,

Alan
