Public Key Accelerator (PKA) RAM is Not Byte Accessible
Revision B
When accessing the PKA RAM, the RAM is not byte accessible. If a single byte is accessed (read or written), 4 bytes will be accessed instead.
The workaround is to use word access (4 bytes) when accessing the PKA RAM.
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.
