LDC can be used to generate images in variety of views. Depending on the use case, some parts of the input image are not used. In order to reduce on-chip memory size requirement in circular buffer mode, only required part of the image is stored. Starting co-ordinate of the stored frame can be configured in IBUF_PIX_START register. Default values on of (StartX,StartY) are zero making backward compatible with previous version (J7ES PG1).
Using programmable StartY, Circular buffer start can be aligned with image stored in the local memory. Due to 16-byte alignment requirement on Base address, following restrictions apply on StartX.
