There are no flags affected by this instruction.
Function
When the execution condition for IL(002) is OFF, the outputs for all instructions between IL(002) and
ILC(003) are interlocked. When the execution condition for IL(002) is ON, the instructions between
IL(002) and ILC(003) are executed normally.
The following table shows the treatment of various outputs in an interlocked section between IL(002)
and ILC(003).
Note Bits and words in all other instructions including TTIM(087), TTIMX(555), SET, RSET, CNT, CNTX(546),
CNTR(012), CNTRX(548), SFT, and KEEP(011) retain their previous status.
