Status and Error Register
The load status drawing shows the logical relationship between the status registers. Three of the
registers, the condition (CON) register, the error (ERR) register, and the status (STA) register
reflect the condition of the load.
Two of the registers, the fault shutdown mask (SDN) and the fault latch mask (LAT) control
which of the condition register bits cause a load shutdown (shutdown mask) and/or are latched
until read (latch mask).
The summary bit enable (SBE) register controls that condition bits are passed through to the
system status register (STA). The system status register is available either in response to an STA?
query or in response to an IEEE-488 bus serial poll.
The service request (SRQ) enable mask controls which bits in the status register can assert the
SRQ line.
