Hello-

APB stands for "Advanced Peripheral Bus". In the DS90UB949-Q1 and DS90UH949-Q1, the APB interface complies to the APB protocol specification and is used to access HDMI control registers and EDID SRAM. In the DS90UB947-Q1 and DS90UH947-Q1, the interface does not comply to the HDMI APB protocol and is used to access device Die ID and device configurations (indirect hidden registers).

Davor

Davor-san,

Thank you for your support.
