External control pins
8.12.1
DSP1
For external control two input pins have been
implemented. The status of these pins can be changed by
applying a logic level. The status is saved in the DSP1
status register. The function of each pin depends on the
DSP1 program.
To control external devices two output pins are
implemented. The status of these pins is controlled by the
DSP program.
Function of these ‘control pins’ can be found in a separate
manual and is rom_code dependent.
8.12.2
DSP2
For external control four configurable I/O pins have been
implemented. Via the I2C-bus these four pins can be
independently configured as input or output. The status of
these pins can be changed by applying a logic level (input
mode). The status is saved in the DSP2 status register.
The function of each pin depends on the I2C-bus setting
and DSP2 program.
Function of these ‘control pins’ can be found in a separate
manual and is rom_code dependent.
8.13
I2C-bus control (pins SCL and SDA)
General information about the I2C-bus can be found in
“The I2C-bus and how to use it”. This document can be
ordered using the code 9398 393 40011. For the external
control of the SAA7706H device a fast I2C-bus is
implemented. This is a 400 kHz bus which is
downward-compatible with the standard 100 kHz bus.
There are two different types of control instructions:
Instructions to control the DSP program, programming
the coefficient RAM and reading the values of
parameters (level, multipath etc.)
Instructions controlling the data flow; such as source
selection, IAC control and clock speed.
The detailed description of the I2C-bus and the description
of the different bits in the memory map is given in
Chapter 9.
