[53] REGULATORS: Current consumption in normal voltage mode is higher in System ON idle

This anomaly applies to IC Rev. Engineering A, build codes QKAA-AB0.

Domains

Application

Symptoms

Current consumption is higher in System ON idle.

Conditions

DC/DC mode is enabled in the VREGMAIN regulator and the device is in System ON idle.

Consequences

Current consumption is higher than expected.

Workaround

When enabling the DC/DC mode in VREGMAIN, apply the following code: 

*((volatile uint32_t *)0x50004728ul) = 0x1;
