Pin Function
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.
Shared Data Bus bit 4. Data D4 access when CMD=0. Address A4 access when CMD=1.
Shared Data Bus bit 3. Data D3 access when CMD=0. Address A3 access when CMD=1.
Shared Data Bus bit 2. Data D2 access when CMD=0. Address A2 access when CMD=1.
3.3V, 2.5V or 1.8V digital VDD input power supply for IO with well decoupling capacitors.
Shared Data Bus bit 1. Data D1 access when CMD=0. In 8-bit mode, this is address A1
access when CMD=1. In 16-bit mode, this is “Don’t care” when CMD=1.
Shared Data Bus bit 0. Data D0 access when CMD=0. In 8-bit mode, this is address A0
access when CMD=1. In 16-bit mode, this is “Don’t care” when CMD=1.
8 or 16-bit bus mode select during power-up / reset:
NC or Pull-up (default ) = 16-bit bus
Pull-down = 8-bit bus
This pin value is also latched into register CCR, bit 6/7.
EEPROM select during power-up / reset:
Pull-up = EEPROM present
NC or Pull-down (default ) = EEPROM not present
This pin value is latched into register CCR, bit 9.
Endian mode select during power-up / reset:
Pull-up = Big Endian
NC or Pull-down (default) = Little Endian
This pin value is latched into register CCR, bit 10.
When this pin is no connect or tied to GND, the bit 11 (Endian mode selection) in
RXFDPR register can be used to program either Little (bit11=0 default) Endian mode or
Big (bit11=1) Endian mode.
