Keithley 6514 User Manual

13-16 Status Structure
The commands to read the condition registers are listed in Table 13-4. For details on reading
registers, see “Reading registers”.
Event registers
As Figure 13-1 shows, each status register set has an event register. When an event occurs,
the appropriate event register bit sets to 1. The bit remains latched to 1 until the register is reset.
Reading an event register clears the bits of that register. *CLS resets all four event registers.
The commands to read the event registers are listed in Table 13-5. For details on reading reg-
isters, see “Reading registers”.
