STATus:PRESet
Status Byte Register
108
Clears all status group event registers. Presets the status group enables
PTR and NTR registers as follows:
ENABle = 0x0000, PTR = 0xffff, NTR = 0x0000
The Status Byte summary register reports conditions from the other status
registers. Data that is waiting in the instrument's output buffer is
immediately reported on the "Message Available" bit (bit 4) for example.
Clearing an event register from one of the other register groups will clear
the corresponding bits in the Status Byte condition register. Reading all
messages from the output buffer, including any pending queries, will clear
the "Message Available" bit. To set the enable register mask and generate
an SRQ (service request), you must write a decimal value to the register
using the *SRE command.
