Stdi_Data_Valid_Raw; Cp_Lock, Cp_Unlock - Analog Devices ADV7850 Hardware Manual

stdi_data_valid_raw

15.5.2
stdi_data_valid_raw is programmable as either an edge-sensitive bit or a level-sensitive bit using stdi_data_valid_edge_sel. Note that this
control also configures whether an interrupt is generated only on the rising edge of stdi_data_valid_raw, or on both edges.
stdi_data_valid_edge_sel, IO, Address 0x41[4]
This control is used to configure the functionality of the stdi_data_valid interrupt. The interrupt can be generated when STDI changes
to an STDI valid state. Alternatively, it can be generated to indicate a change in stdi_valid status.

cp_lock, cp_unlock

15.5.3
cp_unlock_raw is programmable as either an edge-sensitive bit or a level-sensitive bit using cp_lock_unlock_edge_sel. Note that this
control also configures whether an interrupt is generated only on the rising edge of cp_unlock_raw or on both edges.
cp_lock_unlock_edge_sel, IO, Address 0x41[5]
This control is used to configure the functionality of the cp_lock and unlock interrupts.

cp_unlock_st, IO, Address 0x43[3] (Read Only)
This readback indicates the latched signal status of the CP unlock interrupt signal. Once set, this bit remains high until the interrupt is
cleared via cp_unlock_clr. This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt mask bit.
