Difference between AIO and GPIO pins for tms320f28027

Hi,

My responses below -

1.I need more GPIO pins to control the relays at output circuit

However, I have used all GPIO pins

So can I use AIO pins to ouput high and low pulses

>> Yes you can use AIOs for this purpose.

2. Can I set, clear and toggle AIo pins.

>> Yes.

3.is internal pullup valuable for AIO pins

>> No internal Pull available.

4. What is difference between GPio and AIO pins considering functions

>> AIOs are shared with analog function. Refer to device datasheet for operating params.
