Identification. For DiskOnChip 16MB/32MB, up to four chips can be
cascaded in the same memory window, according to the following
assignment:
Chip 1 = ID1, ID0 = VSS, VSS (0,0); required for single chip
Chip 2 = ID1, ID0 = VSS, VCC (0,1)
Chip 3 = ID1, ID0 = VCC, VSS (1,0)
Chip 4 = ID1, ID0 = VCC, VCC (1,1)
For DiskOnChip 64MB, up to two chips can be cascaded in the
same memory window, according to the following assignment:
Chip 1 = ID1=VSS, ID0 = VSS; required for single chip
Chip 2 = ID1=VSS, ID0 = VCC
Interface Configuration, 1 for 16-bit interface mode, 0 for 8-bit
interface mode.
Lock, active low. When active, provides full hardware data
protection of selected partitions.
Busy, active low, open drain. Indicates that DiskOnChip is
initializing and should not be accessed. A 10 K
required even if the pin is not used.
Interrupt Request. Requires a 10 K
Reset, active low.
