6.4 KEYSTORE_ERR_01

KEYSTORE Module

Category

Functional

Function

STATUS.STAT value can be 0 or 1 without key access

Description

STATUS.STAT has a reset value of 1 and turns to 0 under these conditions: 1. After reset, debugger access via the register window returns 0x00. 2. After reset, the first CPU read returns 0x01, while subsequent CPU reads return 0x00. 3) After reset, first reading any other KEYSTORE register and then reading STATUS.STAT return 0x00.

Workaround

STATUS.STAT=0x0 means "No Error" . For checking if a slot is valid or not (Whether key is present), check STATUS.VALID.
