In decode case, current external SDRAM Bit
Stream Buffer read address of process index 0 is
set to this register by BIT processor.
In encode case; host must set current external Bit
Stream Buffer read address of process index 0 to
this register.
This register is updated at every bit stream data
load by BIT processor and wrapped around by
automatically.
* Current design load 512 bytes to internal buffer
for each transfer. Therefore Bit Stream Read
Pointer is increased
to
512 after loading data
completion.

In decode case; host must set current external Bit
Stream Buffer write address of process index 0 to
this register.
In encode case, current external SDRAM Bit
Stream Buffer write address of process index 0 is
set to this register by BIT processor.
This register is updated at every bit stream data
save by BIT processor and wrapped around by
automatically.
* Current design save 512 bytes from internal
buffer for each transfer. Therefore Bit Stream
Write Pointer is increased
to
512 after saving data
completion.
