Condition Codes
PS022517-0508
The C, Z, S, and V flags control the operation of the conditional jump (JP cc and JR cc)
instructions. Sixteen frequently useful functions of the flag settings are encoded in a 4-bit
field called the condition code (cc), which forms Bits 7:4 of the conditional jump
instructions. The condition codes are summarized in
codes can be created using more than one assembly code mnemonic. The result of the flag
test operation decides if the conditional jump is executed.
