Page 142 The event status registers are numbered 0 to 2, and are each 8-bit registers; they correspond to bits ESB0 to ESB3 of the status byte. Each bit has a particular 3194 event allocated to it. The constituent bits are masked by the corresponding event status enable register, then the summary (logical OR) is copied to one of bits 0 to 2 (ESB0- ESB2) of the status byte (STB).

Page 145 ──────────────────────────────────────────────────── (6) Event status registers 2 (ESR2) This register monitors for out-of-range inputs to the 9605-01 HARMONIC MEASURMENTS UNIT. Its value is therefore all zeros unless the optional 9605-01 is installed. Bits 1 to 6 correspond to the harmonic analysis boards for channels 1 to 6. However, since a maximum of three harmonic analysis boards can be selected simultaneously, no more than three bits can ever be set.
