DESCRIPTION
HOST PROCESSOR INTERFACE
48-51
53-56
Data Bus 0-7
D0-D7
I/O24
The data bus connection used by the host
microprocessor to transmit data to and from
the chip. These pins are in a high-impedance
state when not in the output mode.
44
nI/O Read
nIOR
I
This active low signal is issued by the host
microprocessor to indicate a read operation.
45
nI/O Write
nIOW
I
This active low signal is issued by the host
microprocessor to indicate a write operation.
46
Address Enable
AEN
I
Active high Address Enable indicates DMA
operations on the host data bus.
Used
internally
to
qualify
appropriate
address
decodes.
28-34
41-43,
97
I/O Address
A0-A10
I
These host address bits determine the I/O
address to be accessed during nIOR and
nIOW cycles. These bits are latched internally
by the leading edge of nIOR and nIOW. All
internal address decodes use the full A0 to
A10 address bits.
21,52,
99
DMA Request
A, B, C
DRQ_A
DRQ_B
DRQ_C
O24
This active high output is the DMA request for
byte transfers of data between the host and
the chip.
This signal is cleared on the last
byte of the data transfer by the nDACK signal
going low (or by nIOR going low if nDACK was
already low as in demand mode).
22,36,
96
nDMA
Acknowledge
A, B, C
nDACK_A
nDACK_B
nDACK_C
I
An active low input acknowledging the request
for a DMA transfer of data between the host
and the chip.
This input enables the DMA
read or write internally.
35
Terminal Count
TC
I
This signal indicates to the chip that DMA data
transfer is complete.
TC is only accepted
when nDACK_x is low. In AT and PS/2 model
30 modes, TC is active high and in PS/2
mode, TC is active low.
