47 XTAL1
ESR2_9
I
Sp/M Crystal Oscillator Amplifier Input
To clock the device from an external source, drive
XTAL1, while leaving XTAL2 unconnected.
Voltages on XTAL1 must comply to the core
supply voltage V_DDIM.
I
St/B ESR2 Trigger Input 9
48 PORST
I
In/B Power On Reset Input
A low level at this pin resets the XC2723X
completely. A spike filter suppresses input pulses
<10 ns. Input pulses >100 ns safely pass the filter.
The minimum duration for a safe recognition
should be 120 ns.
An internal pullup device will hold this pin high
when nothing is driving it.

-
PS/B Reference Voltage for A/D Converters ADC0
-
PS/B Reference Ground for A/D Converters ADC0
-
PS/M Digital Core Supply Voltage for Domain M
Decouple with a ceramic capacitor, see Data
Sheet for details.
All V_DDIM pins must be connected to each other.
-
PS/B Digital Pad Supply Voltage for Domain B
Connect decoupling capacitors to adjacent
V_DDP/V_SS pin pairs as close as possible to the pins.
-
PS/-- Digital Ground
All V_SS pins must be connected to the ground-line
or ground-plane.
