This anomaly applies to IC Rev. Engineering A, build codes SICA-BAA.
Symptoms
Some access ports lock up when reading IDR.
Consequences
AP scan fails when encountering these locked APs.
Workaround
Use one of the following solutions:
- Use Nordic Semiconductor programming tools.
- If an AP read times out on an unknown AP, write 0x0000001F to DP->ABORT to stop
the transfer and continue the session.
Note: This item will be fixed on the production version of nRF9160-SICA.
