专家，您好： 我正在使用 2个 DRV8714-Q1EVM 构成4个H桥，驱动汽车的4个 CDC 电磁阀 。目前在实车应用中遇到了一个关于控制逻辑和寄存器配置的问题，请求协助。 1. 硬件背景 控制端： 实车控制器可以提供 4 路 PWM 输出信号 ，具备 CAN 和 LIN 通讯，但 没有 SPI 信号输出 。 驱动端： 使用2个 DRV8714-Q1 驱动 4 个 CDC 电磁阀。 2. 技术需求 我期望在实车运行过程中，控制器实时发出PWM信号 ，实时改变电磁阀的电流在，并且能够在以下三种模式间的实时切换（参考自 《浅析汽车空气悬架系统中的电机驱动应用》 https://e2echina.ti.com/blogs_/b/behindthewheel/posts/53597 ）： 导通 (Drive) ：增加电磁阀电流，调节阻尼力。 慢速续流 (Slow Decay) ：在 PWM 关断期间减小电流纹波，保持阻尼力平稳。 快速续流 (Fast Decay) ：在需要瞬时改变阻尼力时，迅速排空感应电流。 3. 待确认的问题 (Key Questions) A: 现我是否可以用一个CAN转SPI硬件，来使得控制器控制H桥的3种2工作模式，如果可以的话，有参考资料可以学习吗？ B： 或者根据我的需求和现有硬件，有没有其他方案可以解决这个问题？
