[1] I2S: Excessive power consumption after using STOP task

This anomaly applies to IC Rev. Engineering A, build codes SICA-BAA.

Symptoms

Current consumption too high (~900 µA) after using the STOP task.

Conditions

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

Consequences

Current consumption higher than specified.

Workaround

Apply the below 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;
