Product data sheet
8.2.4.2 Exiting shutdown mode
The TDA8026 performs the following steps when exiting shutdown mode:
1. Card insertion on card slot 1 is signalled by the IRQN pin signal being driven LOW.
2. Using the IRQN pin signal, the microcontroller detects the card insertion and drives
3. When the SDWNN pin is HIGH, the IRQN pin is set to HIGH and the analog module is
4. When the TDA8026 is ready, the IRQN pin is set to LOW
5. The microcontroller detects the device interrupt using the IRQN pin and services it
