SPI interface

The following parameters apply to the serial bus communication when SPI protocol has

been selected at start-up. For the other electrical characteristics of the pins, Section 3.4.8

applies.

Warning

When the TDA7705 is not powered on, the internal ESD protection diodes pull-down keep

the I2C/SPI lines connected to ground. This implies that the I2C/SPI bus connected to the

TDA7705 may not be used to drive other devices when the TDA7705 is powered off.
