new_ms_info_st, IO, Address 0x7A[3] (Read Only)
This readback indicates the latched status for the New MPEG Source InfoFrame interrupt. Once set, this bit remains high until the
interrupt is cleared via new_ms_info_clr. This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt mask bit.

1
new_spd_info_st, IO, Address 0x7A[2] (Read Only)
This readback indicates the latched status for the new source product descriptor InfoFrame interrupt. Once set, this bit remains high
until the interrupt is cleared via new_spd_info_clr. This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt mask
bit.

new_audio_info_st, IO, Address 0x7A[1] (Read Only)
This readback indicates the latched status for the new audio InfoFrame interrupt. Once set, this bit remains high until the interrupt is
cleared via new_audio_info_clr. This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt mask bit.

HDMI Edg INT Status 2 register consists of the following fields.
fifo_near_ovfl_st, IO, Address 0x7F[7] (Read Only)
This readback indicates the latched status for the audio FIFO near overflow interrupt. Once set, this bit remains high until the interrupt
is cleared via fifo_ovfl_clr. This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt mask bit.
Function
fifo_near_ovfl_st

1
fifo_underflo_st, IO, Address 0x7F[6] (Read Only)
This readback indicates the latched status for the audio FIFO underflow interrupt. Once set, this bit remains high until the interrupt is
cleared via fifo_underflo_clr. This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt mask bit.
