Description
Address Lines
Data Bus
Byte High Enable. With A0, defines byte accessed for
16 bit wide bus cycles.
I/O Chip Selects
ROM or Flash ROM Chip Select
DiskOnChip or NAND Flash Chip Select
Transceiver Data Enable Control. Active low for Sub-
ISA data transfers. The signal timing is as follows:
• In a read cycle, TRDE# has the same timing as RD#.
• In a write cycle, TRDE# is asserted (to active low) at
Memory or I/O Read. Active on any read cycle.
Memory or I/O Write. Active on any write cycle.
I/O Read. Active on any I/O read cycle.
I/O Write. Active on any I/O write cycle.
DiskOnChip or NAND Flash Read. Active on any mem-
ory read cycle to DiskOnChip.
DiskOnChip or NAND Flash Write. Active on any mem-
ory write cycle to DiskOnChip.
Interrupt 9 Request Input. Active high.
Note:
I/O Channel Ready
Note:
the time WR# is asserted. It continues being asserted
for one PCI clock cycle after WR# has been negated,
then it is negated.
If IRQ9 function is selected but not used, tie
IRQ9 low.
If IOCHRDY function is selected but not used, tie
IOCHRDY high.
