TABLE 3-2 IEEE-488.2 COMMON COMMANDS
COMMAND NAME
DESCRIPTION
Clears all event registers summarized in
the status byte, except for "Message Avail-
able," which is cleared only if *CLS is the
first message in the command line.
Sets "Event Status Enable Register" to
<value>. <value> is an integer between
0 and 255, whose binary equivalent cor-
responds to the state (1 or 0) of bits in the
register. If <value> is not between 0 and
255, an Execution Error is generated.
EXAMPLE: decimal 16 converts to
binary 00010000 which sets bit 4 to a
logical 1.
8099 returns the <value> of the "Event
Status Enable Register" set by the *ESE
command. <value> is an integer whose
binary equivalent corresponds to the state
(1 or 0) of bits in the register.
8099 returns the <value> of the "Event
Status Register" and then clears it. <value>
is an integer whose binary equivalent
corresponds to the state (1 or 0) of bits
in the register.

488.2 CONFORMANCE INFORMATION
The IEEE 488.2 Standard mandated a list of common commands that are common
to all IEEE 488.2 compatible devices. The 8099 responds to these commands
and to some optional common commands defined in the IEEE-488.2 Standard.
Table 3-2 lists how the 8099 responds to these commands and describes their
effect on the 8099 and its status reporting structure.
