Enabling the Event
Status Register
An event status register summary bit (bit 6 of the status byte) will
be set to \1" when any enable bit in the standard event status
register is set to \1". To enable/disable any bits of the standard
event status register, you can set the bits in the standard event
status enable register. These bits correspond to bits in the standard
event status enable register. When a bit is set in the standard event
status enable register it enables the corresp onding bit in the standard
event status register and sets bit 6 of the status byte (event status
register summary bit) to \1". To set any bit in the standard event
status enable register, the *ESE command is used. The syntax of the
*ESE command is:
*ESE < n >
Where, < n > : decimal number (0 to 255)
For example,
If < n > is equal to 34 (00100010), bit 1 and bit 5 are enabled, as
follows.

Bit Pattern
for *ESE command 00100010
When either bit 1 or 5 of the standard ev
ent status register is set to
\1", the event status register summary bit (bit 6 of the status b
yte)
is set to \1".
The default setting is *ESE 0 (all bits of the standard event status
byte are disabled).
Bits 1 and 6 of the event status register are always 0 (zero). Thus
masking these bits has no meaning.
