Status reporting

Status byte

The PA3000 u ses a similar status byte to IEEE 488.2. The PA3000 Status Byte

(STB) contains the ESB and DAS bits. These two bits indicate a

non-zero state in the Standard Event Status Register (ESR) or the Display Data

Status Register (DSR) respectively.

The ESR and DSR each have enable registers, ESE and DSE respectively, set by

the user. These enable registers act as a mask to reﬂect chosen elements of the

appropriate status registers to the Status Byte Register. Setting the appropriate bit

of the enable register to 1 conﬁgures the bits to be summarized in the STB.

If a status byte is read, the DSR and ESR registers are cleared.
