TDA7333
7.7 Programming through Serial bus interface
The serial bus interface is used to access the different registers of the chip. It is able to handle both I2C and SPI
transfer protocols, the selection between the two modes is done thanks to the pin CSN :
– if the pin CSN is high, the interface operates as an I2C bus.
– if the pin CSN is asserted low, the interface operates as a SPI bus.
In both modes, the device is a slave, i.e the clock pin SCL_CLK is only an input for the chip.
Depending on the transfer mode, external pins have alternate functions as following:
Table 7.
Eight registers are available with read or read/write access rights as following :
Table 8.
The meaning of each bit is described below :
