Dialog Enhancement Register
This controls the built-in dialog enhancement algorithm, and
defaults to 0. The maximum setting is 0100000000000000000000
or a twos complement fractional value of 1.0. This algorithm is
intended to solve the problem of playing back high dynamic
range digital audio signals over a television’s built-in speakers. It
provides an amplitude boost to signals that are in the range
where dialog signals are usually found, while at the same time
preventing loud special effects passages from overloading the
speakers or amplifiers.
I2C READ/WRITE DATA FORMATS
The read/write formats of the I2C port are designed to be byte
oriented. This allows for easy programming of common micro-
controller chips. In order to fit into a byte oriented format, 0s
are appended to the data fields in order to extend the data word
to the next multiple of 8 bits. For example, 22-bit words written
to the parameter RAM are appended with two leading zeroes in
order to reach 24 bits (3 bytes). These zero-extended data fields
are appended to a 2-byte field consisting of a read/write bit and
a 10-bit address. The I2C port knows how many data bytes to
expect based on the address received in the first two bytes.
