6r SRQI Service Request Input Bit
6w SRQI IE Service Request Input Interrupt Enable Bit
SRQI is set when:
(CIC & SRQ & -(RQS & DAV)) becomes true or (CIC & SRQ &
RQS & DAV) becomes true.
SRQI is cleared by:
pon + (read ISR2)
Notes
CIC: GPIB Controller-In-Charge
SRQ: GPIB Service Request message
RQS: GPIB Request Service message
DAV: GPIB Data Valid message
pon: Power On Reset
read ISR2: Bit is cleared immediately after it is read
The SRQI bit indicates that a GPIB Service Request (SRQ) message
has been received while the TLC function is active (CIC=1).
Note: The set SRQI equation only applies to situations in which two
or more devices are issuing the SRQ message.
