Note 1. SR 25409 will be ON when 7SEG(––) is being executed.
2. ADBL(––), NEG(––), NEGL(––), and SBBL(––) also affect the signed binary arithmetic flags. Refer to
page 451 for details.
3. SR 25410 will be ON when DSW(––) is being executed.
4. SR 25408 will be ON when MTR(––) is being executed.
Signed Binary Arithmetic Flags
The following table shows the instructions that affect the OF and UF flags. In general, OF indicates that the result of
a 16-bit calculation is greater than 32,767 (7FFF) or the result of a 32-bit calculation is greater than 2,147,483,647
(7FFF FFFF). UF indicates that the result of a 16-bit calculation is less than –32,768 (8000) or the result of a 32-bit
calculation is less than –2,147,483,648 (8000 0000). Refer to Section 5 Instruction Set for details.
Vertical arrows in the table indicate the flags that are turned ON and OFF according to the result of the instruction.
Instructions not shown do not affect any of the flags in the table.
The OF and UF Flags are turned OFF when END(01) is executed, so their status cannot be monitored with a Pro-
gramming Console.
