Push block

nRF54LM20A | nRF54LM20B Datasheet

Push block prevents a key slot from being pushed until the next device reset.

A key slot must be in the PROVISIONED state for a push block to take effect.

To block a key slot from the push operation, perform the following steps:
  1. Configure the key slot ID in the KEYSLOT register.
  2. Trigger the PUSHBLOCK task.

    When the push block has been applied, KMU generates the PUSHBLOCKED event.
