24 MHz Crystal Output
This is the other terminal of the crystal, or a no connect pin, when an
external clock source is used to drive XTALIN/CLKIN.
TEST pin
User must treat as a no connect pin or connect to ground. No trace
or signal should be routed or attached to this pin.
RESET Input
The system can reset the chip by driving this input low. The minimum
active low pulse is 1 μs.
VDD Core Regulator Filter Capacitor
This pin must have a 1.0 μF (or greater) ±20% (ESR <0.1 Ω) capacitor
to VSS.
3.3 V Power
PLL Regulator Filter Capacitor
This pin must have a 1.0 μF (or greater) ±20% (ESR <0.1 Ω) capacitor
to VSS.
Ground Pad / ePad
The package slug is the only VSS for the device and must be tied to
ground with multiple vias.
No Connect
No signal or trace should be routed or attached to these pins.
