Hello experts, I now use s32k144&FS6500 to control the drive, in the program I have released FS0B, and returned success, but the FS0B corresponding level is always low.Consecutive good WD refresh by MCU.
In the FS6500 and FS4500, a write command can be sent by the MCU to request an FS0B activation SF_OUTPUT_REQ register, FS0B_REQ bit. By default, the FS0B_REQ bit is not activated
你好，非常感谢回复，这个SF_OUTPUT_REQUEST寄存器的FS0B_REQ这个比特位的作用是请求FS0B置0，好像不是置为高电平。电源芯片中我未使用FS1B和VAUX，VAUX通过INIT_VAUX_OVUV_IMPACT和REG_MODE这两个寄存器关闭其功能，并且通过读取BIST寄存器发现，LBIST_OK、ABIST2_FS1B_OK、ABIST2_VAUX_OK、ABIST1_OK，都显示OK,但此时错误计数器的值一直为1，并且读到VAUX一直欠压，手册也明确表示当VAUX未使用时，Vaux_UVflag is set and cannot be cleared。所以一直没找到办法去消除错误计数器。如果方便的话可以给我您的例程代码吗？非常感谢!
