Legend:
P = Power supply
I/O = Bi-directional I = Input O = Output.
Ipd = Input with internal pull-down (58K ±30%).
Ipu = Input with internal pull-up (58K ±30%).
Opd = Output with internal pull-down (58K ±30%).
Opu = Output with internal pull-up (58K ±30%).
Ipu/O = Input with internal pull-up (58K ±30%) during power-up/reset; output pin otherwise.
Ipd/O = Input with internal pull-down (58K ±30%) during power-up/reset; output pin otherwise.
I/O (pd) = Input/Output with internal pull-down (58K ±30%).

Pin Function
Shared Data Bus bit 9. Data D9 access when CMD=0. Don’t care when CMD=1.
This pin must be tied to GND in 8-bit bus mode.
Digital ground
3.3V, 2.5V or 1.8V digital VDD input power supply for IO with well decoupling capacitors.
Shared Data Bus bit 8. Data D8 access when CMD=0. Don’t care when CMD=1.
This pin must be tied to GND in 8-bit bus mode.
Shared Data Bus bit 7. Data D7 access when CMD=0. Address A7 access when CMD=1.
Shared Data Bus bit 6. Data D6 access when CMD=0. Address A6 access when CMD=1.
Shared Data Bus bit 5. Data D5 access when CMD=0. Address A5 access when CMD=1.
