INSTRUCTION SET REFERENCE
SETccSet Byte on Condition
Description
This instruction sets the destination operand to 0 or 1 depending on the settings of the status flags
(CF, SF, OF, ZF, and PF) in the EFLAGS register. The destination operand points to a byte
register or a byte in memory. The condition code suffix (cc) indicates the condition being tested
for.
The terms above and below are associated with the CF flag and refer to the relationship
between two unsigned integer values. The terms greater and less are associated with the SF
and OF flags and refer to the relationship between two signed integer values.
