Description
not used
When STDBY is set to logic 1, the chip enters in Standby
mode, and its power consumption is reduced. The IF AGC pin
is set to high-ohmic. The default value is logic 0, which means
that the chip is active.
This signal clears the TDA8295 through the I
(software reset). To activate the reset, just write CLB = 0. This
software reset will not affect the content of the registers.
