本文深入探讨了EPWM-TZ模块的错误联防功能，通过实例讲解了如何利用GPIO触发TZ事件来控制EPWM管脚的状态变化。详细介绍了触发源配置、触发动作设置及触发方式选择，并分享了调试过程中的常见问题及解决方案。

调试目的：

学习和体会EPWM-TZ模块的错误联防功能

例程功能：

简述：GPIO12[TZ1]->INPUT X-BAR->EPWM TZ->EPWM xA
通过外部GPIO引脚触发TZ1事件，从而控制EPWM对应管脚强制
拉高或拉低。

//!  \b External \b Connections \n
//!  - EPWM1A is on GPIO0
//!  - EPWM2A is on GPIO2
//!  - TZ1 is on GPIO12
//!
//! This example also makes use of the Input X-BAR. GPIO12 (the external
//! trigger) is routed to the input X_BAR, from which it is routed to TZ1.
//!
//! The TZ-Event is defined such that EPWM1A will undergo a One-Shot Trip
//! and EPWM2A will undergo a Cycle-By-Cycle Trip.
//!
