VCCA accepts any supply voltage from 1.4 V to 3.6 V. The B port is designed to track VCCB0 and VCCB1. VCCB0 and VCCB1 can accept any supply voltage from 1.4 V to 3.6 V; however, VCCB0, VCCB1, or both must be greater than or equal to VCCA during normal operation. If VCCB0 and VCCB1 are both at GND, the A port is in the high-impedance state. The control pins are supplied by VCCA. 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. Table 1.
