de_regen_lck_st, IO, Address 0x75[0] (Read Only)
This readback indicates the latched status of the DE regeneration lock interrupt signal. Once set, this bit remains high until the interrupt
is cleared via de_regen_lck_clr. This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt mask bit.

The HDMI Edg INT Status 1 register consists of the following fields.
new_isrc2_pckt_st, IO, Address 0x7A[7] (Read Only)
This readback indicates the latched status for the new ISRC2 packet interrupt. Once set, this bit remains high until the interrupt is
cleared via new_isrc2_pckt_clr. This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt mask bit.

new_isrc1_pckt_st, IO, Address 0x7A[6] (Read Only)
This readback indicates the latched status for the new ISRC1 packet interrupt. Once set, this bit remains high until the interrupt is
cleared via new_isrc1_pckt_clr.This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt mask bit.

new_acp_pckt_st, IO, Address 0x7A[5] (Read Only)
This readback indicates the latched status for the new ACP packet interrupt. Once set, this bit remains high until the interrupt is cleared
via new_acp_pckt_clr. This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt mask bit.

new_vs_info_st, IO, Address 0x7A[4] (Read Only)
This readback indicates the latched status for the new vendor specific InfoFrame interrupt. Once set, this bit remains high until the
interrupt is cleared via new_vs_info_clr. This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt mask bit.
