the logic values at pin MD[6] during RESET is used to determine memory configuration (1 -
256Kx16 with “2 CAS with 1 WE” or “1 CAS with 2 WE” type DRAMs.) The pinout diagram is
labelled with the pin names for the default configuration of single 256Kx16 DRAM with 2 CAS
and 1 WE signals. The MD[6] pin has an internal pullup resistor, so no external resistor is
required for this default case. Refer to the following table for details.
