8/9
1 If the peripheral is present on the device (see Table –)
2 A weak pull-up can be enabled on PE5 input and open drain output by configuring the PEOR register
and depending on the PE5PU bit in the option byte.

X
Bidirectional. This active low signal forces the
initialization of the MCU. This event is the top
priority non maskable interrupt. This pin is
switched low when the Watchdog has triggered
or VDD is low. It can be used to reset external
peripherals.
