Description

• The 32-bit data or 32-bit equivalent constant speciﬁed by S1 is divided by the 32-bit data or 32-

bit equivalent constant speciﬁed by S2 when the trigger turns ON. The quotient is stored in D+1

and D and the remainder is stored in the special data registers DT9016 and DT9015.

■ Flag condition

• Error ﬂag (R9007): Turns ON and keeps the ON state,

- when the area speciﬁed using the index modiﬁer exceeds the limit.

- when the 32-bit equivalent constant or 32-bit data for the divisor

speciﬁed by S2 is 0.

The error address is transfeered to DT9017 and held. (See notes below.)

• Error ﬂag (R9008): Turns ON for an instant,

- when the area speciﬁed using the index modiﬁer exceeds the limit.

- when the 32-bit equivalent constant or 32-bit data for the divisor

speciﬁed by S2 is 0.

The error address is transferred to DT9018. (See notes below.)

• = ﬂag (R900B): Turns ON for an instant when the calculated result is recognized as “0”.

• Carry ﬂag (R9009): Turns ON for an instant when negative minimum value K-2147483648

(H80000000) is divided by K-1 (HFFFFFFFF).

Notes:

• Special data registers DT9017 and DT9018 are available only for FP1s with CPU

version 2.7 or later. (All FP1s with a sufﬁx “B” on the part number have this function.)

• When using special internal relays R9008, R9009, and R900B as the ﬂags for this

instruction, be sure to program the ﬂags at the address immediately after the

instruction.

• Refer to page 223, “8-3. Table of Special Internal Relays”, for details about error

ﬂags, = ﬂag, and carry ﬂag.

Dividend data Divisor Trigger turns ON Quotient Remainder

S1 : lower 16-bit

S2 : lower 16-bit D : lower 16-bit DT9015

S1+1 : higher 16-bit S2+1: higher 16-bit D+1 : higher 16-bit DT9016

• When processing 32-bit data, the higher 16-bit areas S1+1, S2+1, D+1 are automatically decided if the

lower 16-bit areas S1, S2, D are speciﬁed.

e.g., S1+1 (higher) = DT201, S1 (lower) = DT200

S2+1 (higher) = DT101, S2 (lower) = DT100

D+1 (higher) = DT1, D (lower) = DT0
