The three registers are considered logically concatenated and compose the Global Frame Counter as de-
scribed in the table.
It is updated at every decoded MPEG Frame. The registers are reset on both hardware and software reset.
AVERAGE_BITRATE
Address: 0x6A (106)
Type: RO
Software Reset: 0x00
Hardware Reset: 0x00
AVERAGE_BITRATE is a read-only register and it contains the average bitrate of the incoming bitstream
divided by two.
The value is rounded with an accuracy of 1 Kbit/sec.
SOFTVERSION
Address: 0x71 (113)
Type: RO
After the STA015 boot, this register contains the version code of the embedded software.
RUN
Address: 0x72 (114)
Type: RW
Software Reset: 0x00
Hardware Reset: 0x00
