Input Schmitt Triggers
All the Logic Input pins have builtin Schmitt trigger
circuits to prevent the NCN6000 against uncontrolled
operation. The typical dynamic characteristics of the related
pins are depicted in Figure 33.
The output signal is guaranteed to go High when the input
voltage is above 0.70*Vbat, and will go Low when the input
voltage is below 0.30*Vbat.
The CLOCK_IN pin has been design to provide a 40 MHz
bandwidth clock receiver input, capable to drive the internal
clock divider. This front end circuit yields a constant Duty
Cycle signal, according to the ISO specification, to the
external smart card, even when the NCN6000 division ratio
is 1:1.

Interrupt Function
The NCN6000 flags the external microprocessor by pulling down the INT signal provided in pin 9. This signal is activated
by one of the here below referenced operations.

Leaving the INT pin Low has no influence on the
NCN6000 internal behavior. It is up to the engineering to
decide when and how the interrupt will be cleared from this
pin. As described before, this can be achieved by either
providing a Chip Select positive transient, or by starting the
DCDC converter with the standard command PWR_ON =
H and CS =L.
