Cases where rewriting is not possible during RUN
1. When the result of rewriting is a syntax error.
<Example>
When executing the rewriting which does not form the following pair of instructions.
1. Step ladder instructions (SSTP/STPE)
2. Suroutine instructions (SUB/RET)
3. Interrupt instructions (INT/IRET)
4. JP/LBL
5. LOOP/LBL
6. MC/MCE
Also, rewritng is not possible during RUN in case of other syntax errors.
2. During the forced input/output operation
Interrupt restrictions
When using interrupt, high-speed counter, pulse output or PWM output functions, do not perform a
rewrite during RUN.
If a rewrite during RUN is executed, the operation as below will be performed. Exercise caution.
1. Interrupt programs will be disabled. Enable by executing an ICTL instruction once again.
<Example> Using R9034 (rewrite during RUN completed flag)
2. The high-speed counter will continue to count.
Target value match on/off instructions (F166/F167) will continue.
Coincidence interrupt programs will be disabled when the F166/F167 instruction is running.
3. Pulse output and PWM output will be stopped.
