CARD DETECTION
The card detector circuit provides a constant low current to
bias the CRD_DET_A and CRD_DET_B pins, yielding a
logic High when no card is present and the external switch is
Normally Open type. The internal logic associated with pins
20 and 41 provides a programmable selection of the slope
card detection. The transition is filtered out by the internal
digital filter circuit, avoiding false interrupt. In addition to
the typical 50 s delay, the MPU shall provide an additional
delay to cope with the mechanical stabilization of the card
interface (typically 1 ms), prior to valid the CRD_VCC_A or
CRD_VCC_B supply.
When a card is inserted, the detector circuit asserts
INT = Low as depicted before, the external P being
responsible to clear the interrupt signal, taking the
necessaries actions. When the NCN6004A detects a card
extraction, the power down sequence is automatically
activated for the related interface section, regardless of the
PWR_ON state, and the INT pin is asserted Low. It is up to
the external MPU to clear this interrupt by pulsing the CS
pin.

The interrupt signal can be cleared either by a positive
going slope on the Chip Select pin as depicted in Figure 11,
or by forcing the PWR_ON signal High (keeping CS = Low)
for the related card.
The polarity of the card detection switch can be either
Normally Open or Normally Close and is software
controlled as defined here below and in Table 2.
