I simply want to connect a GPIO to GIOB[2] on pin 55. Is this possible?
I am using a PGE QFP (144 pin) package. In spns162c it lists the MIBSPI3NCS[0]/AD2EVT/GIOB[2]/N2HET2_PIN_nDIS on pin 55 with a discription of:
"The application cannot output a level onto this terminal when it is configured as GIOB[2]. A pull-up is enabled 20 μA on this input. This pull cannot be disabled, and is not programmable using the GIO module pull control registers."
When looking at the pinmux settings in halcogen 4.06.00 for pin 55, I can only find the MIBSPI3NCS[0] and AD2EVT, but no GIOB[2].
Table 4-1 of spnu499b mentions the multiplexed pin of GIOB[2] is 55, but the dedicated pin is 142 (I don't see this anywhere in spns162; in fact pin 142 is something entirely different). In 4.3.3 of spnu499b it mentions connecting the N2HET2 to the MIBSPI3NCS[0]/AD2EVT for a fault detection (which is apparently how the GIOB[2] multiplexing is used?). PINMMR29[16] is set to 1 for multiplexing. But it seems like if GIOB[2] multiplexing is on, it needs to be connected to either the MIBSPI or AD2EVNT modules?
When I poll GIOB[2] in software, I'm not getting any response.
Thanks,
