MUX_MODE = Low
The bi-directional switch Q9 is OFF and the I/O signals
are routed straightforward to their appropriate outputs. The
two I/O lines can operate simultaneously, depending upon
the P capabilities, regardless of the CARD_SEL signal
logic level.
The pull up resistors, on the P side of each I/O line, can
be connected or not as defined by the EN_RPU signal.
PARALLEL OPERATION
MUX_MODE = High
The bi-directional switch Q9 is ON and the I/O_A pin is
used to handle data for CARD_A and CARD_B. The signal
MULTIPLEXED OPERATION
is routed to the appropriate card by means of the
CARD_SEL logic signal. In this mode, the I/O_B pin 19
must be left open since the internal data signal will be
present on this pin.
Moreover, since R1 and R3 are in parallel, the pull up
resistor R1 is automatically disconnected to maintain the I/O
line impedance to 20 k (typical), what ever be the
EN_RPU logic level. This feature makes sure the current
flowing trough the external card is limited to 500 A during
a low level state.
