I want to use DMMDATA[0]-[15], RTP_DATA[0]-[15], these pins as a normal purpose GPIO, Please provide me example codes, library functions for the same.

void gioSetDirection(gioPORT_t *port, uint32 dir)

What should I write in place of *port?

As DMMDATA and RTP_DATA is 16 bit only and dir is 32 bit, what should be the value of dir?

give me small example here?

Reply me as soon as possible.

Hello,

You can use DMM and RTP pins as GIO signals, and can use GIO APIs:

gioSetDirection(rtpPORT, dir);

gioSetDirection(dmmPORT, dir);

rtpPORT and dmmPORT are defined in reg_rtp.h and reg_dmm.h

I want to use GIOA[0] and GIOA[1] in for external interrupt.

How to configure and how to detect individual interrupt?

Give us small example here:?

1. Enable GIO interrupt as mentioned in Whong's post

2. Enable the GIO interrupt is VIM module (channel 9 or channel 23). Channel 9 is for high priority, but channel 23 is for lower priority. If low priority is selected in #1, you need to use VIM channel 23: GIO Low
