- What do I need to do to set the TMS9914A GPIB Controller into an
- online state, i.e. turn the IFC line on.
-
- I have tried:
-
- setting swrst
- setting interrupt Mask 0 to (BI+BO+ENDB)
- writing the controller address (0x00)
- setting IFC
- clearing swrst
- clearing IFC
- sending remote enable
-
- The above commands come from the TMS9914A data manual provided by TI.
-
- I have also tried other combinations of the above commands to no
- avail. The only state that the controller seems to be in is with ATN
- false (HIGH).
-
- Any help would be appreciated.
