SPC58xx Voltage monitor configuration Technical note

2021-12-09
● Introduction:
■ The SPC58xx devices are a wide family of Power Architecture® based microcontrollers that offer the needed scalability to be used in different automotive applications (like vehicle body, gateway, automotive powertrain controllers and so on).
■ These microcontrollers include a robust power management infrastructure that enables the applications to monitor internal voltages for high- and low-voltage conditions. The monitoring capability is also used to ensure the supply voltages and the internal voltages are within the required ranges before the microcontroller can leave the reset.
■ This document describes how to configure the SPC58xx voltage monitoring in two different ways:
▲ By Hardware, using the Device Configuration Format (DCF) Record
▲ By Software, using the registers of the Power management controller (PMC)
■ After a brief introduction that describes the Power Management Controller Digital interface (PMC_Dig) and the DCF client, some configuration examples are given.
■ The concepts and topics shown in this document are common to all SPC58xx families.
