PROGRAMMING AND STATUS FUNCTIONS
The NCN6004A includes a programming interface and a
status interface. Figure 4 illustrates the sequence one must
follow to enter and exit the programming mode. Table 1 and
Table 2 provide the logical functions associated with the
input and output signals. The parameters are latched upon
the rising edge of the PGM signal, the CS pin being held low.
Any number of programming sequences can be performed
while the CS pin is Low, but the minimum timings must be
observed.

Example:
Set CRD_VCC_A = 3.0 V
Example:
Set CRD_CLK_B = 1/8
On the other hand, since the programming data are latched
upon the rising edge of the PGM signal, the most up to date
selected card (using CARD_SEL = H or L) is used to
activate the associated card. Consequently, when both cards
must be updated with the same programmed content, a dual
PGM sequence must be carried out, changing the
CARD_SEL signal during the High level state of the PGM
pin.
Although selecting a card in possible during the same
Chip Select sequence (as depicted here above), the user must
make sure that no data will be present to a card not ready for
such a function. As a matter of fact, all the card signals are
routed to the selected card immediately after a CARD_SEL
change, the NCN6004A taking no further logic control prior
to activate the swap. To avoid any risk, one can run a
sequence with the selected card, return CS to High, change
the CARD_SEL according to the expected card selection,
and pull CS to Low to activate the selected card.
