characteristics. The pins of Port 5 also serve as the (up to 4)

analog input channels for the A/D converter, where P5.x

equals ANx (Analog input channel x, x=0...3).

The following pins of Port 5 also serve as timer inputs:

P5.14

T4EUD

GPT1 Timer T4 Ext.Up/Down Ctrl.Input

P5.15

T2EUD

GPT1 Timer T5 Ext.Up/Down Ctrl.Input

XTAL1

XTAL2

XTAL1:

Input to the oscillator amplifier and input to the

internal clock generator

XTAL2:

Output of the oscillator amplifier circuit.

To clock the device from an external source, drive XTAL1,

while leaving XTAL2 unconnected. Minimum and maximum

I/O

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.

The following Port 3 pins also serve for alternate functions:
