The value of ‘0’ means BIT processor is ready for
host command.
The value of ‘1’ means BIT processor is executing
host command and not completed yet.
Host must check this bit before write RunCommand
register. If this bit is ‘1’, host must wait until the value
of ‘0’ to set command.

Command code
3’b001 (SEQ_INIT): Encode/Decode sequence
initialize. In encode case, BIT processor analysis
encoding parameter and encode sequence header.
In decode case, BIT processor decode sequence
header and report sequence header information.
3’b010 (SEQ_END): Terminates Encode/ Decode
sequence. In encode case, BIT processor flush
internal bit stream buffer to external bit stream
buffer. In decode case, BIT processor terminates
process
3’b011 (PICURE_RUN): Encode/Decode one
picture. BIT processor encodes/decodes one picture.
