Query
RQS?
Returns the weighted sum of all enabled status register bits.
Description
The
RQS
command enables one or more bits in the status register. When an enabled condition occurs,
the SRQ line is asserted. All other conditions and bits are not supported, and thus are always 0. To
enable multiple bits, add up the individual bit weights.
The
SRQ
command must be sent to enable SRQ.
Example
RQS 32
SRQ on error.
RQS 160
SRQ on error and data available.

Description

state. These states are saved by the
SSTATE
command. Note that the number of valid saved states
depends on the amount of installed memory as indicated above.
