Overview

This user guide describes the NXP IEC60730B library, which provides self-test functions for Arm Cortex-M0+ based microcontrollers to meet international safety standards including IEC 60730, IEC 60335, UL 60730, and UL 1998. The library includes core-dependent tests for CPU registers, program counters, stack, and memory (RAM/Flash), as well as peripheral-dependent tests for clocks, digital and analog I/O, watchdogs, and touch-sensing interfaces. It supports multiple NXP MCU families such as Kinetis MKV1x, MKLxx, MKE0x, MKE1xZ, MKW3x, K32L2Axx, K32L2Bxx, and LPC series (LPC51U68, LPC84x, LPC86x, LPC82x, LPC80x). The document includes details on library implementation, function sizes, and execution times for IAR, Keil, and MCUXpresso IDEs.
