cables and the absolute value of the internal pullup device play almost no role in determining rise and fall
times on the BKGD pin.
2.4.4
General-Purpose I/O and Peripheral Ports
The remaining pins are shared among general-purpose I/O and on-chip peripheral functions such as timers
and analog comparator. Immediately after reset, all of these pins are configured as high-impedance
general-purpose inputs with internal pullup/pulldown devices disabled.
NOTE
To avoid extra current drain from floating input pins, the reset initialization
routine in the application program should either enable on-chip
pullup/pulldown devices or change the direction of unused pins to outputs.

Pullup/Pulldown1
1 SWC is software-controlled pullup/pulldown resistor; the register is associated with the respective port.
Alternative Functions2
2 Alternative functions are listed lowest priority first. For example, GPIO is the lowest priority alternative function of the
PTA0 pin; ACMP+ is the highest priority alternative function of the PTA0 pin.
