In order to limit the band width hogging by LDC in case of wrong mesh table data, maximum amount of input block pixel data being fetched will be capped at maximum internal memory available for respective data (Note: Luma and Chroma has different size internal buffers).
In YUV420* modes, limit is imposed by Luma data. Pixel data fetch is stopped on detecting the overflow condition and interrupt event is generated. Maximum of 2 requests can be issued upon overflow detection. In case of mesh data, only interrupt event is generated on detecting overflow condition and there is no stalling of fetch. These events are generated for the first overflow case per frame.
