95 The Trusted Base System Architecture (TBSA-M) defines non-volatile (NV) counters
96 or version counters as a counter with the following properties:
107 Trusted non-volatile counters can be used to store the value of security
108 counters per updatable software image. Ideally all independently updatable
116 Currently the NV counters can be manipulated through the interface described
119 NV counters and anti-rollback protection
121 Trusted non-volatile counters might not be supported by a hardware platform.
151 the new image's security counters against the security counter stored in
152 non-volatile counters.

182 counters operations. This API detaches the use of NV counters from the TF-M NV

189 based on TF-M NV counters implementation provided by the platform.
269 To have a platform independent way to access the NV counters, TF-M defines a
279 shorter write endurance of the assets storage device and the NV counters
