VCCA
VCCA powers all A-port I/Os and control inputs.
VCCB0 powers 1B, 2B, 3B, 4B, 9B1, and 10B1.
VCCB1 powers 5B, 6B, 7B, 8B, 9B2, 10B2, 11B, 12B, and 14B.

device operation
The A port is designed to track V
CCA
. V
CCA
accepts any supply voltage from 1.4 V to 3.6 V. The B port is designed
to track V
CCB0
and V
CCB1
. V
CCB0
and V
CCB1
can accept any supply voltage from 1.4 V to 3.6 V, however, V
CCB0
,
V
CCB1
, or both must be greater than or equal to V
CCA
during normal operation. If V
CCB0
and V
CCB1
are both at GND,
the A port is in the high-impedance state. The control pins are supplied by V
CCA
. The microprocessor is connected
to the A port, and the memory card(s) are connected to the B port. The device can be configured using MODE0,
MODE1, CS0, and CS1 pins to interface with 1-bit, 4-bit, or 8-bit memory cards. Outputs 12A and 14B are push-pull
and open drain (OD), respectively, except for NAND flash (XD) mode, where they are open drain and push-pull,
respectively.
