Application

Current consumption is too high after using the STOP task.

I2S was running and was stopped by triggering the STOP task.

Current consumption is higher than specified.

Apply the following code after the STOP task. For secure mode:


*((volatile uint32_t *)0x50028038) = 1;
*((volatile uint32_t *)0x5002803C) = 1;

For non-secure mode:


*((volatile uint32_t *)0x40028038) = 1;
*((volatile uint32_t *)0x4002803C) = 1;
