Reset Circuit and Distribution
The DMx Processor is reset from switch 9 (PORn), switch 3 (warm reset), or from the system reset
(FT2232HL). The DMx processor provides reset out to camera, Ethernet PHY, audio codec, and
FT2232HL. The camera module is reset from an AND operation of reset out from the DMx processor and
camera reset GPIO. The Ethernet PHY is reset from an AND operation of reset out from the DMx
processor and Ethernet reset GPIO. See
to configure GPIOs for camera- and Ethernet-reset
functionality.
