Description for turn on diagnosis
This IC can determine whether the conditions listed below occur or not at turn ON:
-Short to GND
-Short to VCC
-Output to output short
-Speaker open
As first “switch on”, the write data is sent to “turn ON” the IC.
If the turn on diagnostic is activated at this time, the write data, with the diagnostic cycle byte: IB1
D6 set at 1, is sent at the same time
The result of self diagnosis can be obtained from the read data sent after the turn on diagnostic
data permitted time, as below Figure:
