7.12 MOD Division Remainder Double Integer (32-Bit)
Format
Description
Status word
MOD
MOD (remainder of the division of 32-bit integer numbers) divides the contents of
ACCU 2 by the contents of ACCU 1. The contents of ACCU 1 and ACCU 2 are
interpreted as 32-bit integer numbers. The result of the instruction is stored in
accumulator 1. The result gives only the division remainder, and not the quotient.
(The instruction /D can be used to get the quotient.)
The instruction is executed without regard to, and without affecting, the RLO. The
status word bits CC 1, CC 0, OS, and OV are set as a function of the result of the
instruction.
The contents of accumulator 2 remain unchanged for CPUs with two ACCUs.
The contents of accumulator 3 are copied into accumulator 2, and the contents of
accumulator 4 are copied into accumulator 3 for CPUs with four ACCUs. The
contents of accumulator 4 remain unchanged.
