A
AnACPU and AnUCPU dedicated instructions
■Method of expression of dedicated instructions
Dedicated instructions based on the LEDA, LEDB, LEDC, SUB, and LEDR instructions, that are used with the AnACPU or
AnUCPU have been changed for the same format as the basic instructions and the application instructions for the QCPU,
LCPU.
The instructions that cannot be converted due to the absence of the corresponding instructions in the QCPU, LCPU are
converted into OUT SM1255/OUT SM999 (for the Q00J/Q00/Q01CPU).
The instructions that have been converted into OUT SM1255/OUT SM999 should be replaced by other instructions or
deleted.
■Dedicated instructions whose names have been changed
Dedicated instructions for the AnUCPU or AnACPU which have the same instruction name as is used for basic instructions
and application instructions have undergone name changes in the QCPU, LCPU.
