Detailed Description

Registers, Bit Masks and Bit Positions for the Infoblock.

Defines used for accessing the information block

Macro Definition Documentation

INFOBLOCK_ICE_LOCK_OFFSET

#define INFOBLOCK_ICE_LOCK_OFFSET   0x30

The offset inside the information block where the SWD locking information is stored.

Note

There are four locking locations starting at 0x30 for location 0, 0x32 for location 1, 0x34 for location 2, and 0x36 for location 3

INFOBLOCK_KEY_SIZE

#define INFOBLOCK_KEY_SIZE   64

The length in bytes of the ECDSA public key.

Note

This is the raw length. Once stored, 2 of every 8 bytes is used for CRC15, so the stored length is greater than 64 bytes.

Enumeration Type Documentation

lineformat_e

enum lineformat_e

Three information block line types.

USN: No CRC15, ignore lowest 15 bits [14:0]

RAW: No CRC15

DESIGN: Use CRC15 error detection in bits [62:48].

Enumerator
INFOBLOCK_LINE_FORMAT_USN	USN format is unique, ignore lowest 15 bits
INFOBLOCK_LINE_FORMAT_RAW	Raw data format, use all bits
INFOBLOCK_LINE_FORMAT_DESIGN	Design format, has CRC15 in bits 62:48, bit 63 is a line locking bit
