Card VCC, Card CLOCK and Card Detection
Polarity Programming
The CRD_VCC and CLOCK_IN programming options
allows matching the system frequency with the card clock
frequency, and to select 3.0 V or 5.0 V CRD_VCC supply.
The CRD_DET programming option allows the usage of
either Normally Open or Normally Close detection switch.
Table 3 highlights the A0, A1, PGM and I/O logic states for
the possible options. The default power up reset condition
is state 1: asynchronous clock, ratio 1/1, CRD_CLK
active, CRD_DET = Normally Open, CRD_VCC = 3.0 V.
All states are latched for each output variable in
programming mode at the positive going slope of Chip
Select [CS] signal. It is the system designer’s responsibility
to set up the options needed to match the chip with the
peripherals. In particular, when using Normally Close
switch, the CRD_DET polarity must be defined during the
first cycles of the initialization.

CRD_VCC
9. The programmed conditions are latched upon the Chip Select (CS, pin 6) positive going transient.
10. Card clock integrity is guaranteed no spikes whatever be the frequency switching.
11. The STATUS register is not affected when the NCN6000 operates in any of the programming functions.
12. The CRD_VCC and CRD_CLK are not affected when the NCN6000 operates outside their respective decoded logic address.
13. The High Level on STATUS in registers $00 to $0F, inclusive, having being implemented to reduce current consumption but have no other
meanings.
14. At turn on, the NCN6000 is initialized with CRD_VCC = 3.0V, CLOCK_IN Ratio = 1/1, CRD_CLK = START, CRD_DET = Normally Open.
