This command reads the WD2 Counter value. Not the WDT Preset value
that is defined by the “
<CR>” command.
NOTE 2:
In case that WD2 is not operated, this command will yield an error and it
will show WDT predefined value.
NOTE 3:
This command, in addition to reading WD2 Counter value, sets the WD2
Counter value to its Preset value.
NOTE 4:
Each reading might yield a different value as it is depended on the time
elapse since previous reading and presetting.
