POINTS
(1) Since EGP and EGF instructions are executed according to the results of operation
performed immediately before the EGP/EGF instruction, these instructions must be used in
the same position as the AND instruction (refer to 5.1.1.).
An EGP and EGF instruction cannot be used at the position of an LD or OR instruction.
(2) EGP and EGF instructions cannot be used at the circuit block positions shown below.
