ADV7612 User Guide says ”The HPA_A and HPA_B pins is open drain. An external pull-up resistor is required to pull it high.(Page31)"
On the other hand, There is description that INT2 is drove high or low (Page 170 INT2 polarity control).
Is a pull-up resister needed when HPA_A is configured for INT2?
And, Does INT1 and INT2 differ in polarity on initial register setting?
