optional input is received while they are being output.

5-6-7 Clearing M500 to M999 with Forced Block End or G74
The M strobe and M code outputs for M codes 500 to 999 won’t be output cleared
if the program block that outputs the M code is cleared with the Forced Block End
signal (PC data area interface bit) or the OPTIONAL END function (G74), but
previous M codes won’t be cleared.
Example 5 The M strobe and M code won’t be output if a Forced Block End signal is
received before they are output, but a previous M code and M strobe won’t be
cleared.
