Description
PIO9
(1)
PFI
(1)
E1
I/O [4mA]
IN
Power-fail Interrupt (Schmitt Trigger Input, Active HIGH with Pull-
up)
This pin can be used as a power fail interrupt.
PFI is a non-maskable interrupt (NMI). It can be used to save non-
volatile data to the internal flash or external memory devices (see
chapter 6.7).
It can also be used as PIO[9].

IN
Interrupt In (Schmitt Trigger Input, Active HIGH with Pull-down)
These pins are external interrupt input requests.
Note: INT3 is shared with the USB controller and INT1 is shared
with the MAC 1 controller.
PIO30

INT5#
(1)
A3
I/O [4mA]
IN
Interrupt In (Schmitt Input with Pull-up, Active LOW)
This pin can be used as INT5. Note: This interrupt is shared with
UART 3.
It can also be used as PIO[30].
