PKA_01

Public Key Accelerator (PKA) Interrupt Line is Always High When Module is Enabled and PKA is Idle

Revisions Affected:

Revision B

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) available in all versions of the SimpleLink Software Development Kit (SDK) that support this device.
