43.3.3.2.1 PUKCL_HEADER Structure
The PUKCL_HEADER is common for all services of the library. This header includes standard fields to
indicate the requested service, sub-service, options, return status, and so on, as shown in the following
tables.
Different terms used in the below description to be understood, are as follows:
• Parameter – Represents a variable used by the PUKCL. Every parameter belongs to either
PUKCL_HEADER or PUKCL Service Specific Header
• Type – Indicates the data type. For details on data type, please refer to
CryptoLib_typedef_pb.h file in the library
• Dir – Direction. Indicates whether PUKCL considers the variable as input or output. Input means that
the application passes data to the PUKCL using the variable. Output means that the PUKCL uses the
variable to pass data to the application.
• Location – Suggests whether the parameter need to be stored in Crypto RAM or device SRAM. The
PUKCL driver has macros for placing parameters into Crypto RAM, so that the user does not have to
worry about the addresses
• Data Length – If a parameter is a pointer variable, the Data Length column shows the size of the data
pointed by the pointer
