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

ANC_DATA_1

0x5A

ANC_DATA_2

0x5B

ANC_DATA_3

0x5C

ANC_DATA_4

0x5D

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.
