During initialization of the codec a subset of configuration registers and coefficient RAM
(CRAM) locations has to be programmed to set the configuration parameters according
to the application and desired features.
The codec can be programmed via microcontroller interface (see chapter 2.1) or the
IOM-2 MONITOR channel (see chapter 2.2.4).
The coefficient RAM (CRAM) can generally be programmed in power-up as well as in
power-down mode. However, due to the general possibility of concurrent accesses of the
ARCOFI
To ensure the error free programming of the CRAM, it’s recommended to delay the
access after switching from power-down to power-up ( or after switching from power-up
to power-down respectively) by a setup time of 4 IOM-2 frames plus the setup time of the
oscillator, i.e in total about 5 ms.
An ARCOFI
chapter 4.8.1) which allows using the SOP, COP and XOP command sequences of the
ARCOFI.
The codec can also be programmed by addressing the configuration registers and
coefficient RAM (CRAM) locations directly (see chapter 4.8.2).
The following two chapters 4.8.1 and 4.8.2 give an overview of the access to the codec
parameters.
For more detailed information about the individual parameters refer to the corresponding
sections in the functional and register description of the codec.
4.8.1
This programming sequence is compatible to the SOP, COP and XOP command
sequences of the ARCOFI. It gives indirect access to the codec registers 60
the CRAM (80
number of data bytes (data n; n = 0, 1, 4 or 8). The number of data bytes depends on the
codec command. The commands can be applied in any order and number. The coding
of the different SOP, COP and XOP commands is listed in the description of the
command word (CMDW) in chapter 4.8.1.1.
