I
Power saving mode enable / Start watchdog
timer
A low level on this pin allows the software to enter
the power down, idle and slow down mode. In case
the low level is also seen during reset, the watchdog
timer function is off on default.
Use of the software controlled power saving modes
is blocked, when this pin is held on high level. A high
level during reset performs an automatic start of the
watchdog timer immediately after reset. When left
unconnected this pin is pulled high by a weak
internal pull-up resistor.
