我启用了默认的FlexCAN_Ip_Example_S32K344中的引脚配置工具，以在正常模式下观察PTA7引脚上的CAN0 Tx输出。我能够在示波器上看到数字 CAN 信号。
但是当我将输出端口从 PTA7 更改为 PTB1 时，我在示波器上看不到任何信号。
我也尝试将 CAN0 改为 CAN1，但仍然只能看到来自 PTA7 端口的信号。
有什么原因导致我无法从 PTA7 以外的任何端口观察到 CAN 信号，因为在原理图中 PTA7 和 PTB1 都可以有 CAN0_Tx 信号。
我正在使用 S32K3X4EVB-T172 板并附加了该项目。
我有 PCAN-USB CAN 解码器，当 CAN0 Tx 引脚为 PTA7 时可以正常接收消息，但当我将其更改为 PTB1 时，我没有收到任何消息。CAN0 中只能使用 1 个引脚进行传输吗？
