STA003T
The Ancillary Data extraction on STA003T can be
described as follow:
STA003T has a specific 5 bytes Ancillary Data
buffer, mapped into the I2C registers:
0x59
0x5A
0x5B
0x5C
0x5D
ANC_DATA_1
ANC_DATA_2
ANC_DATA_3
ANC_DATA_4
ANC_DATA_5
Since the content of Ancillary Data into an MPEG
Frame is max. 56 bytes, a specific register, to re-
quire new 5 bytes, is needed.
This register is:
0x16
CMD_INTERRUPT
The interrupt register, is sensitive to any non-zero
value written by the Microcontroller. When this
register is updated the Ancillary Data buffer is
filled up with new values and the registers
0x41
ANCCOUNT_L
0x42
ANCCOUNT_H
are updated (decremented) accordingly.
