High−level Instructions
3 − 71
Outline Subtracts 16-bit data from the minuend and stores the result in the
specified area.
For the FP0R/FPΣ/FP−X/FP0/FP−e, the P type high−level instruction
“P27 (P−)” is not available.

Description
Subtracts the 16-bit data or 16-bit equivalent constant specified by S2 from the 16-bit data or 16-bit equivalent
constant specified by S1. The subtracted result is stored in D.

Flag conditions
・Error flag (R9007): Turns on and stays on when the area specified using the index modifier
exceeds the limit.
・Error flag (R9008): Turns on for an instant when the area specified using the index modifier
exceeds the limit.
・= flag (R900B): Turns on for an instant when the calculated result is recognized as “0”.
・Carry flag (R9009): Turns on for an instant when the calculated result exceeds the range of 16-bit
data (overflows or underflows).
