3) Processing by High Performance model QCPU
If all SD64 to SD79 anunciator Nos. are switched OFF, the "USER"
LED on the High Performance model QCPU front display is switched
OFF.
POINT
If an error occurs to continue operation with the higher-priority over an anunciator
when the anunciator is switched ON, eliminate the error by executing an LEDR
instruction. See Section 7.20.2 for priority. In this case, executing an LEDR
instruction will not switch the anunciator OFF. To switch the anunciator OFF, you
must first eliminate the error before executing the LEDR instruction because the
error takes priority over the anunciator.
