Port 3 is a 15-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 3 outputs can be configured as
push/pull or open drain drivers. The input threshold of Port 3
is selectable (TTL or special).
The following Port 3 pins also serve for alternate functions:
T0IN
CAPCOM1 Timer T0 Count Input
T6OUT
GPT2 Timer T6 Toggle Latch Output
CAPIN
GPT2 Register CAPREL Capture Input
T3OUT
GPT1 Timer T3 Toggle Latch Output
T3EUD

GPT1 Timer T3 Count/Gate Input
T2IN
GPT1 Timer T2 Count/Gate/Reload/Capture Inp.
MRST

Oscillator Watchdog Enable. This input enables the oscillator
watchdog when high or disables it when low e.g. for testing
purposes. An internal pull-up device holds this input high if
nothing is driving it.
For normal operation pin OWE should be high or not
connected.
In order to drive pin OWE low draw a current of at least
200
A.
