Supply
VSS — These pins provide ground for chip logic and I/O
drivers.

Supply
ADC Analog Ground — This pin supplies an analog ground
to the ADC modules.
OCR_DIS

K14
Input
On-Chip Regulator Disable —
Tie this pin to VSS to enable the on-chip regulator.
Tie this pin to VDD to disable the on-chip regulator.
This pin is intended to be a static DC signal from
power-up to shut down. Do no try to toggle this pin for
power savings during operation.
VCAP1*
62
K8
Supply
VCAP1 - 4 — When OCR_DIS is tied to VSS (regulator
enabled), connect each pin to a 2.2
μF or greater bypass
capacitor in order to bypass the core logic voltage regulator,
required for proper chip operation. When OCR_DIS is tied to
VDD (regulator disabled), these pins become VDD_CORE and
should be connected to a regulated 2.5V power supply.
Note: This bypass is required even if the chip is powered
with an external supply.

* When the on-chip regulator is disabled, these four pins become 2.5V VDD_CORE.
VPP1

A7
Input
VPP1 - 2 — These pins should be left unconnected as an
open circuit for normal functionality.
VPP2
2C2
CLKMODE
99
H12
Input
Clock Input Mode Selection — This input determines the
function of the XTAL and EXTAL pins.
1 = External clock input on XTAL is used to directly drive the
input clock of the chip. The EXTAL pin should be grounded.
0 = A crystal or ceramic resonator should be connected
between XTAL and EXTAL.
EXTAL
94
J12
Input
External Crystal Oscillator Input — This input can be
connected to an 8MHz external crystal. Tie this pin low if
XTAL is driven by an external clock source.
