Table 123. Additional Symbols
Assignment of a value is indicated by an arrow. For example,
indicates the source data is added to the destination data and the result is stored in the des-
tination location.
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 instruc-
tions. The condition codes are summarized in
be created using more than one assembly code mnemonic. The result of the Flag test oper-
ation decides if the conditional jump is executed.
