The Q table entry addressed in the previous register is available to the
host in this register.
Internal microcontroller Program Counter (PC). Note that the LSB should
always be read before the MSB to ensure correct capture of the
microcontroller PC value.
The value in this register is the revision number of the L64105.
Setting this bit causes the Video Decoder to start decode/reconstruction
of pictures. Clearing the bit stops the decode process but does not stop
the channel. The current status of decoding can be monitored by reading
the Decode Status Interrupt bit (Register 0, bit 0,
