5.3 System Status and Configuration Module (SSCM)
5.3.1 Introduction
The primary purpose of the SSCM is to provide information about the current state and configuration of
the system that may be useful for configuring application software and for debug of the system.
On microcontrollers with a separate STANDBY power domain, the System Status block is part of that
domain.

5.3.2 Features
The SSCM includes these features:
• System Configuration and Status
— Memory sizes/status
— Microcontroller Mode and Security Status (including censorship and serial boot information)
— Search Code Flash for bootable sector
— Determine boot vector
• Device identification information (MCU ID Registers)
• Debug Status Port enable and selection
• Bus and peripheral abort enable/disable
