Function
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 µA.
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).
