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?
