Enable Register

The enable register enables reporting of the event bits to the summary bit or the status byte. The contents of the enable register are unchanged by *CLS and *RST.

Transition Filters

A positive transition filter allows an event to be reported when a condition changes from false to true. Setting both positive and negative filters to TRUE allows an event to be reported any time the condition changes. Clearing both filters disables event reporting.

The contents of transition filters are unchanged by *CLS and *RST.

The status registers maybe be divided into 4 categories, the operation status registers, the questionable status registers, the standard event status register and the status byte.

OPERation Status Register

The operation status register is a 16-bit register which contains information about conditions which are part of the power supply’s normal operation.

The Operation Status data structure has the operation status register and 5 sub-registers to represent regulation, shutdown, protection shutdown, remote control, and current sharing modes. Each of the sub-registers is summarized in a summary bit.

Figure represents the Operation Status data structure. The “+” represents the logical summation of bits in a register. Table 4.9, Table 4.10, Table 4.11, Table 4.13, and Table 4.14 describe the meanings of each bit as well as the bit number and bit weight.
