Chapter 2 Pins and Connections
When IRQ is configured as the IRQ input and is set to detect rising edges, a pulldown device rather than
a pullup device is enabled.
In EMC-sensitive applications, an external RC filter is recommended on the IRQ pin. See
an example.
2.3.7
The remaining pins are shared among general-purpose I/O and on-chip peripheral functions such as timers
and serial I/O systems. Immediately after reset, all of these pins are configured as high-impedance
general-purpose inputs with internal pullup devices disabled.
For information about controlling these pins as general-purpose I/O pins, see
Input/Output.” For information about how and when on-chip peripheral systems use these pins, refer to the
appropriate chapter from

To avoid extra current drain from floating input pins, the reset initialization
routine in the application program should either enable on-chip pullup
devices or change the direction of unused pins to outputs so the pins do not
float.
