TDA7705
Function description
Doc ID 15938 Rev 8
Figure 5.
SPI modes
In the case of the TDA7705, the data are latched on the clock's rising edge, with CPOL = 1
and CPHA = 1 (mode 3 in the figure above). According to the specification of this mode, the
polarity of the CLK line when no communication is taking place is high.
A "write" communication example is shown in the figure below, for an unspecified number of
bits (see the relevant technical documentation for frame structure description):
Figure 6.
SPI "write" sequence
The start condition is signaled by the CS line going low, and the stop condition by the CS
line going high. It is not allowed to toggle the CS line while the communication is going on.
A "read" communication example is shown in the figure below, for an unspecified number of
bits (see the relevant technical documentation for frame structure description ):
Figure 7.
SPI "read" sequence
The red line is controlled by the TDA7705, whereas the black lines are controlled by the P.
