Ctrl. Type Function
137 XTAL1
138 PORST
I
Sp/1 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_DDI1.
I
In/B Power On Reset Input
A low level at this pin resets the XC228x
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.
139 ESR1
O0 / I St/B External Service Request 1
EX0AINB
I
St/B External Interrupt Trigger Input
140 ESR2
O0 / I St/B External Service Request 2
EX1AINB
I
St/B External Interrupt Trigger Input
141 ESR0
O0 / I St/B External Service Request 0
Note: After power-up, ESR0 operates as open-
drain bidirectional reset with a weak pull-up.
