nRF91 Series uses special debug locking mechanism. To gain access to debugging features the following steps should be performed: 1) UICR registers should be configured to enable debug port. 2) User application should set corresponding registers to open access to debug port.

Optionally J-Link can perform a full chip erase, to temporarily reopen debug access until next power reset.
