This register indicates the base address for storing the decoded JPEG Images. When bit 4 of Control register is set as
‘0’( Separate Address Use ), the Rendering Base Start Address should be specified. When bit 4 of Control Register is set as
‘1’( Image Capture Engine Frame Buffer Use ), the value of this register has no affect.
Both Local and Texture memory are supported. For Texture memory, bit 5 of Control Register should be set to ‘1’.
The Rendering Base Start Address Register is set using 1 MByte unit.

Interrupt Status bit indicates whether the operation of writing one frame image into Memory has completed or not. This bit
is set to one whenever a frame image is written into memory. This bit will be cleared when bit 2 of JPEG Decoder Command
Control register is asserted to ‘1’.
The value in X / Y Image Size register is not the real image size value. The real image size value can be calculated by
multiplying X / Y Size with 32. For example, when X Image Size Register has a value of 20, the Real X Image Size shall be
640 (20 x 32).
