Identification. Configuration control to support up to
four chips cascaded in the same memory window.
Chip 1 = ID1, ID0 = VSS, VSS (0,0); must be used
Chip 2 = ID1, ID0 = VSS, VCCQ (0,1)
Chip 3 = ID1, ID0 = VCCQ, VSS (1,0)
Chip 4 = ID1, ID0 = VCCQ, VCCQ (1,1)
Lock, active low. When active, provides full
hardware data protection of selected partitions.
Interface Configuration, 1(VCCQ) for 16-bit
interface mode, 0 (VSS) for 8-bit interface mode.
Busy, active low, open drain. Indicates that
DiskOnChip is initializing and should not be
accessed. A 10 KΩ pull-up resistor is required if
this pin drives an input. A 10 KΩ pull-up resistor is
recommended even if this pin is not used.
Reset, active low.
