XOUT/P2.7

I/O

Output terminal of crystal oscillator

General-purpose digital I/O pin

RST/NMI/SBWTDIO

Reset or nonmaskable interrupt input

Spy-Bi-Wire test data input/output during programming and test

TEST/SBWTCK

Selects test mode for JTAG pins on Port1. The device protection fuse is

connected to TEST.

Spy-Bi-Wire test clock input during programming and test

VCC

Supply voltage

VSS

Ground reference

DVCC

Digital supply voltage

AVCC

Analog supply voltage

QFN Pad

Package

Pad

QFN package pad connection to VSS recommended.

NOTE: If XOUT/P2.7 is used as an input, excess current will flow until P2SEL.7 is cleared. This is due to the oscillator output driver connection

to this pad after reset.
