Pin explanation
Dedicated input ports.
These ports are designed with a low threshold voltage.
Input is disabled in Backup mode.

The mode (input or output) is set using the IOS2 instruction.
PB2

Backup mode.
These ports are set up as general-purpose input ports after a power
on reset.

I/O General-purpose I/O ports (middle-voltage input and output).
The mode (input or output) is set using the IOS2 instruction.
External pull-up resistors are required since the output circuits are
open drain.
Input is disabled and the pins go to the high-impedance state in
Backup mode.
These ports are set up as general-purpose input ports after a power
on reset.
I/O General-purpose I/O and external interrupt shared function ports.
The input formats are Schmitt inputs.
The external interrupt function is enabled when the external interrupt
enable flag is set.
• When used as general-purpose I/O ports :
The mode (input or output) is set in 1-bit units using the IOS2
instruction.
• When used as external interrupt pins :
The external interrupt functions are enabled by setting the
corresponding external interrupt enable flag (INT4EN or INT5EN).
In this case, the pins must be set to input mode in advance.
Input is disabled and the pins go to the high-impedance state in
Backup mode.
These ports are set up as general-purpose input ports after a power
on reset.
