CRD_DET Input Voltage (card extracted)
Digital Filter Delay
INTERRUPT
Chip Select Acknowledge or Clear Interrupt
Figure 12. Card Extraction Detection and Interrupt Signals
When the card is extracted, the CRD_DET signal
generates an interrupt, assuming the positive pulse width is
longer than the digital filter. The oscillogram, Figure 12,
depicts the behavior for a Normally Open switch.
Note: since the internal pull up resistor is relatively high
(500 k typical), one must use a 10 M input impedance
probe to read this signal.
CRD_DET Input Voltage (card inserted)
INTERRUPT
Chip Select
Figure 13. Interrupt Acknowledgement During a Card Insertion Detection Sequence
The interrupt signal, provided pin 9, is cleared by a
positive going Chip Select signal as depicted by the
oscillogram, Figure 13. The CS pulse width is irrelevant, as
long as it is larger than 2.0 s, to activate a different
sequence. Leaving the interrupt signal Low has no influence
on the internal behavior of the NCN6000, but will be
automatically cleared when the DCDC will be activated by
the MPU (CS=L, PWR_ON = Positive High transition)
