8.4 Power-down mode
9.1 I
It should be noted that the level control is always operating.
The strategy of the level detection has to be adapted for each type of channel decoder. It
must be defined to satisfy ADC sampling (minimum level, ADC headroom).
All AGC amplifiers are controlled independently.
The TDA18218HN can be programmed in Standby mode. The following blocks are turned
off when programming a power-down:
Remaining functions are:

to the bus. The SDA pin provides bidirectional data transfer. While the SCL pin provides
the timing sequences. Data can be read and written as follows:

Any register can be written to using its subaddress
Any following (contiguous) registers can be written using the subaddress of the first
register
The read after Restart mode is not allowed. In addition, registers cannot be read using
the subaddress of the register. However, registers can be read as follows:
– from 00h to 16h
– from 00h to 27h
– from 00h to 3Ah
– from 00h to any register subaddress, if MSB = 1 for the next register
