TMS320F28335: TMS320F28335

Part Number: TMS320F28335

As i am using zero crossing detection for one of analog input signal which gives me the digital signal h1 or 0.

To sense this active high and active low signals. GPIO is fine or interrupt configuration is fine.

Or any special pins present already in TMS320F28335 controller for ZCD detectioon

Which pins are preferred mostly.

I used these pins GPIO 13, GPIO 14, GPIO 15, 

  • XINT1 XINT2, and XNMI interrupts can accept inputs from GPIO0–GPIO31 pins.
  • XINT3–XINT7 interrupts can accept inputs from GPIO32–GPIO63 pins.

GPIO13  ZCD 1

GPIO14  ZCD 2

GPIO15  ZCD 3

Please advice
