我在sent接收的过程中遇到了下面问题

接收的第一帧数据正常,后面接收的数据FIR中断标志位就会置1(This bit is set after a Synchronization / Calibration pulse was received that deviates more than +- 25% from the nominal value. The referring data is ignored.)关于频率我没有找到原代码位置

请解答一下谢谢

Hi @do-while 

1. 确认MCU和sensor设置了相同的tick值,以保证通讯正常

2. 可以示波器重点看下第二帧数据的sync

3. 频率的设置,参考https://github.com/Infineon/AURIX_code_examples/tree/master/code_examples/iLLD_TC397_ADS_SENT_Redund...
