Common memory function When the REG# signal is set to a high level common memory is selected. -Read mode When each memory IC in the card are switched, the control registers of each memory IC are set to read only mode. Operation of the card then depends on the four possible combinations of CE1# and CE2# (note WE# should be set to a high level when the device is in read mode except during combination (4) where it’s condition is unimportant) : (1) If CE1# is set to a low level and CE2# is set to a high level, the card will work as an eight bit data bus width card. Data can be accessed via the lower half of the data bus (D0 to D7). (2) If both CE1# and CE2# are set to a low level, data will be accessible via the full sixteen bit data bus width of the card. In this mode LSB of address bus (A0) is ignored. (3) If CE1# is set to a high level and CE2# is set to a low level the odd bytes (only) can be accessed through upper half of the data bus (D8 to D15). This mode is useful when handling the odd (upper) bytes in a sixteen bit interface system. Note that A0 is also ignored in this operating condition. (4) If CE1# and CE2# are set to a high level, the card will be in standby mode where it consumes low power. The data bus is kept high impedance. When OE# is set to a low level data can be read from the card, depending on the address applied and the setting of CE1# and CE2# as mentioned above, except under combination (4) When OE# is set to a high level and WE# is set to a high level the card is in an output disable mode -Write mode By using the 4 combinations of CE1# an.
