hancement is going to perform.
For example, in case of a 0 dB signal (max. level) only attenuation would be possible. If enhancement is
desired, the signal has to be attenuated accordingly before in order to reserve a margin in dB.
An increment of a decimal unit corresponds to a Tone Attenuation step of 1.5dB.
ANCILLARY DATA BUFFER
Address: 0x7E - 0xB5 (126 - 181)
Type: RO
Software Reset: 0x00
Hardware Reset: 0x00
The STA015 contains 56 consecutive 8-bit registers corresponding to the maximum number of ancillary
data that may be contained in MPEG frame.
The ANCCOUNT_L and ANCOUNT_H registers contain the number of ancillary data bits available within
the current MPEG frame.
To perform ancillary data reading a status register (0xB6 - INTERRUPT_STATUS_REGISTER) is avail-
able: bit 0 of this register should be polled by the microcontroller in order to understand when new data
are available.
