new_samp_rt_st, IO, Address 0x84[3] (Read Only)
This readback indicates the latched status of the new sample rate interrupt. Once set, this bit remains high until the interrupt is cleared
via new_samp_rt_clr. This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt mask bit

audio_flt_line_st, IO, Address 0x84[2] (Read Only)
This readback indicates the latched status of the new TMDS frequency interrupt. Once set, this bit remains high until the interrupt is
cleared via new_tmds_freq_clr. This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt mask bit.

new_tmds_frq_st, IO, Address 0x84[1] (Read Only)
This readback indicates the latched status of the new TMDS frequency interrupt. Once set, this bit remains high until the interrupt is
cleared via new_tmds_freq_clr. This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt mask bit.

fifo_near_uflo_st, IO, Address 0x84[0] (Read Only)
This readback indicates the latched status for the audio FIFO near underflow interrupt. Once set, this bit remains high until the
interrupt is cleared via FIFO_UFLO_CLR. This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt mask bit.

The HDMI Edg Status 4 register consists of the following fields.
ms_inf_cks_err_st, IO, Address 0x89[7] (Read Only)
This readback indicates the latched status of the MPEG Source InfoFrame checksum error interrupt. Once set, this bit remains high
until the interrupt is cleared via ms_inf_cks_err_clr. This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt mask
bit.
