F.W. BELL Model 7030 Gauss/Tesla Meter Instruction Manual
7-8 Section 7 – Remote Operation
STATUS
(Continued) Each register set consists of three individual registers, as depicted in Figure 7-3 .
The CONDITION register is a real time, read-only register that is constantly
updated to reflect current operating conditions.
The EVENT register is fed by the CONDITION register, but operates as a latch.
Whenever any bit in the CONDITION register goes to “1”, a corresponding “1” is
latched into the EVENT register and remains that way until cleared by a specific
command.
The ENABLE register is a mask register that is used to generate the single status
bit in the STATUS BYTE. Setting any bit in the ENABLE register to “1” will allow
a corresponding “1” in the EVENT register to set the summary bit in the STATUS
BYTE.
An example of their usage appears at the end of this section.
