137 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
138 PORST
I
In/B Power On Reset Input
A low level at this pin resets the XE167xM
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 pull-up device will hold this pin high
when nothing is driving it.
139 ESR1
O0 / I St/B External Service Request 1
After power-up, an internal weak pull-up device
holds this pin high when nothing is driving it.
