The CMOS Sensor Interface, otherwise known as the CSIF, provides an interface for image

capture from CMOS sensors. The device can be connected to the CMOS sensor directly using its

CMOS Sensor Interface. The CSIF supports both Vertical SYNC and Horizontal SYNC modes for

image capture implementation. The CSIF consists of window capture and sub-sampling functions

together with dual FIFOs, each with a capacity of 8 × 32 bits, to store data which can be moved

to the internal SRAM via the Peripheral Direct Memory Access circuitry, PDMA. The CSIF does

not support image data conversion or decode but rather transfers the image data received from the

CMOS sensor to the internal SRAM transparently.
