Hi all,

  • Does WDOGx_B shown in the i.MX8M-Mini data sheet mean the WDOG_B external output signal?

  • Or does it mean the wdog_rst internal signal shown in the reference manual?

We want to know the low width of the WDOG_B external output signal for our product design.

BR,

George

The external WDOG output signal  (similar as WDOG-1 on the picture)

is not controlled in software.

Hello,

  The CC3 parameters relates to external output signal:

"WDOGx_B output signals (for each one of the Watchdog modules) do not
have dedicated pins, but are muxed out through the IOMUX"


Have a great day,
Yuri

Dear Yuri,

Thank you for your reply.

  • Does CC3 parameter for external output signal you say mean red mark in the figure below

  • Can I make the low pulse width longer by Watchdog register settings?
  • Or is this length uncontollable by the user?

BR,

George
