SBC FS6501 how to switch Normal_WD mode to init_FS

WALNUTY — Thu, 13 Jun 2024 07:45:44 GMT

Hi,

I'm try to find a way to switch FS6501 to init_FS from Normal_WD.

In datasheet, I saw that it should be a external RST could work, but doesn't mention how to use it.

Could you help explain the detail to do, like a low pulse from main controller?

BR,

Walnut.

Hi,

You need request RSTB by sending SPI commands: RSTB_REQ in SF_OUTPUT_REQUEST register. Then, a 10ms RSTB low pulse is sent by SBC, SBC state machine will convert to INIT_FS from Normal_WD.
