    Hi Tomohiro,

    When /MR is pulled low, /RESET is held low.  As a result, the watchdog functionality and voltage supervision functionality are ignored.

    Please note that WDI must not transition while /RESET is in a logic low state unless decoupled per the datasheet.

    Very Respectfully,

    Ryan
