VPP /ICCSEL

Flash programming voltage. Must be held low

in normal operating mode.

RESET

I/O

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 trig-

gered or VDD is low. It can be used to reset ex-

ternal peripherals.
