Port 6 is an 8-bit bidirectional I/O port. It is bit-wise programmable for
input or output via direction bits. For a pin configured as input, the
output driver is put into high-impedance state. Port 6 outputs can be
configured as push/pull or open drain drivers.
The Port 6 pins also serve as bus interface signals:

Port 2 is an 8-bit bidirectional I/O port. It is bit-wise programmable for
input or output via direction bits. For a pin configured as input, the
output driver is put into high-impedance state. Port 2 outputs can be
configured as push/pull or open drain drivers.
The Port 2 pins also serve as fast external interrupt inputs:

Oscillator Watchdog Enable. This pin enables the PLL when high or
disables it when low (e.g. to disable the OWD for testing purposes.
An internal pullup device holds this input high if nothing is driving it.
Note
:
The input voltage at pin OWE must not exceed 12.6 V.
For 3 V operation pin OWE must be driven low.
