PKA_01

Public key accelerator (PKA) interrupt line is always high when module is enabled and PKA is idle

Revisions Affected:

Revision E and earlier

Details:

When the PKA module is enabled and idle, the interrupt line is always high and the interrupt can thus not be used as is.

Workaround:

The workaround is to disable the PKA interrupt in the interrupt service routine while the PKA module is idle and re-enable the interrupt right after starting an operation.

The workaround is implemented in the TI-provided cryptography drivers (ECDHCC26X2.c, ECDSACC26X2.c, ECJPAKECC26X2.c_list.c) in the following SimpleLink software development kit (SDK) versions:

  • SimpleLink CC13x2 SDK 1.60.00.xx and later
