TDA8417
Power-on reset
The following actions are carried out by the internal power-on reset when it is active:
The AF outputs are muted
The identification circuit is deactivated (mono)
The control ports (C1 and C2) are set LOW
The I
2
C-bus transceiver is initialized
When the power-on reset becomes passive the following occurs:
The AF outputs are kept in the mute state until the contents of the switch register are changed from (00) hex via the
I
2
C-bus
The identification circuit is activated
The control ports are LOW until the mute and control port register is changed (CR bits 10, 11, 20 and 21)
The I
