Temporary buffer SDRAM byte address
Temporary buffer must be 256 byte-aligned.
Host must writes this register before executing
DEC_SEQ_INIT command
Temporary buffer 2 is used as data partition part 1 save
buffer for mpeg4 and Intra prediction Cb buffer for AVC
and deblocking buffer for VC1.
Temporary buffer 2 must be larger than
stride/2*picHeight/2/16 for AVC, picWidth*10 for VC1.
In case of mpeg4, temporary buffer 2 size is not
estimated.
