new_gamut_mdata_st, IO, Address 0x7F[0] (Read Only)
This readback indicates the latched status for the new gamut metadata packet interrupt. Once set, this bit remains high until the
interrupt is cleared via new_gamut_mdata_pckt_clr. This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt
mask bit.
