Sequence Output Instructions Section 3-3
Description SET turns the operand bit ON when the execution condition is ON, and does
not affect the status of the operand bit when the execution condition is OFF.
Use RSET to turn OFF a bit that has been turned ON with SET.
RSET turns the operand bit OFF when the execution condition is ON, and
does not affect the status of the operand bit when the execution condition is
OFF. Use SET to turn ON a bit that has been turned OFF with RSET.
SET and RSET have immediate refreshing variations (!SET and !RSET).
When an external output bit has been specified for B in one of these instruc-
tions, any changes to B will be refreshed when the instruction is executed and
reflected immediately in the output bit for the CPU Unit built-in output.
The set and reset inputs for a KEEP(011) instruction must be programmed
with the instruction, but the SET and RSET instructions can be programmed
completely independently. Furthermore, the same bit may be used as the
operand in any number of SET or RSET instructions.
Flags No flags are affected by SET and RSET.
Precautions SET and RSET cannot be used to set and reset timers and counters.
When SET or RSET is programmed between IL(002) and ILC(003) or
JMP(004) and JME(005), the status of the specified bit will not be changed if
the program section is interlocked or jumped.
