This anomaly applies to Revision 1, build codes LACA-A0A.
It was inherited from the previous IC revision Engineering A.
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;
*((volatile uint32_t *)0x40028038) = 1;
*((volatile uint32_t *)0x4002803C) = 1;
