HDMI Interrupts Validity Checking Process
All HDMI interrupts have a set of conditions that must be taken into account for validation in the display firmware. When the ADV7619
interrupts the display controller for an HDMI interrupt, the host must check that all validity conditions for that interrupt are met before
processing that interrupt.
For simplicity, HDMI interrupts can be subdivided into three groups, as listed in the following sections.
Group 1 HDMI Interrupts
The interrupts listed in Table 71 are valid irrespective of the mode in which the ADV7619 is configured, that is: HDMI mode
(PRIM_MODE set to values 0x05 or 0x06).

TMDS_CLK_B
CABLE_DET_A
CABLE_DET_B
Group 2 HDMI Interrupts
The interrupts listed in Table 72 are valid on the condition that the ADV7619 is configured in HMDI mode.
