Chip Enable, active low.
Address bus. A0 is multiplexed with the DPD ball.
floating when IF_CFG is set to 0 (8-bit mode).
Data bus, low byte.
Write Enable, active low.
Output Enable, active low.
Identification. Configuration control to support up to
two chips cascaded in the same memory window.
Chip 1 = ID1, ID0 = VSS, VSS (0,0); must be used
Chip 2 = 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 ball drives an input. A 10 KΩ pull-up resistor is
recommended even if this ball is not used.
Reset, active low.
System Clock.
DMA Request, active low. A 10 KΩ pull-up resistor
is required if this ball drives an input. A 10 KΩ pull-
up resistor is recommended even if this ball is not
used.
