Symbol Pin Input Function
Num. Outp.
RSTIN 142 I
Reset Input with Schmitt-Trigger characteristics. A low level
at this pin while the oscillator is running resets the XC167. An
internal pullup resistor permits power-on reset using only a
capacitor connected to V_SS.
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 100 ns + 2 CPU clock cycles.
Note: To let the reset configuration of PORT0 settle and to
let the PLL lock a reset duration of ca. 1 ms is
recommended.

Digital Ground.
Connect decoupling capacitors to adjacent V_DD/V_SS pin
pairs as close as possible to the pins.
All V_SS pins must be connected to the ground-line or ground-
plane.
