DEFAULT

7:0

IRQ HPD Minimum Time

This field defines the minimum amount of time that HPD must be deasserted

for an IRQ event to be recognized. De-assertions for less than this amount of

time shall be ignored.

The programmed time is (50 us * IRQ_HPD_MIN_TIME) + 100 us.

Note:

Software may not change the state of this register while HPD

Enable is set to 1b.

IRQ HPD Maximum Time

This field defines the maximum amount of time that HPD shall be deasserted

for an IRQ event to be recognized. Assertions for more than this amount of

time shall not be determined to be an HPD interrupt event.

The programmed time is (50 us * IRQ_HPD_MAX_TIME) + 100 us.

Note:

Software may not change the state of this register while HPD

Enable is set to 1b.

HPD High Detect Time

This field defines the amount of time that HPD must be asserted, after initially

being low, in order to detect an HPD_HIGH event.

The programmed time is (50 us * HPD_HIGH_DET_TIME) + 100 us.

Note:

Software may not change the state of this register while HPD

Enable is set to 1b.
