PARALLEL CONTROL PORT PINS
Signal Name:
INT*
Signal Description:
Interrupt
Signal Type:
Output
Flags host controller during conditions and change of states as defined in the Status Registers. Active
low, open drain output.
Signal Name:
MUX
Signal Description:
Bus Operation
Signal Type:
Input
Set low to select non-multiplexed bus operation. Set high to select multiplexed bus operation.
Signal Name:
D0 to D7 / AD0 to AD7
Signal Description:
Data Bus or Address/Data Bus
Signal Type:
Input / Output
In non-multiplexed bus operation (MUX = 0), serves as the data bus. In multiplexed bus operation
(MUX = 1), serves as a 8–bit multiplexed address / data bus.
Signal Name:
A0 to A6
Signal Description:
Address Bus
Signal Type:
Input
In non-multiplexed bus operation (MUX = 0), serves as the address bus. In multiplexed bus operation
(MUX = 1), these pins are not used and should be tied low.
Signal Name:
BTS
Signal Description:
Bus Type Select
Signal Type:
Input
Strap high to select Motorola bus timing; strap low to select Intel bus timing. This pin controls the
function of the RD*(DS*), ALE (AS), and WR*(R/W*) pins. If BTS = 1, then these pins assume the
function listed in parenthesis ().
Signal Name:
RD* (DS*)
Signal Description:
Read Input (Data Strobe)
Signal Type:
Input
RD* is an active low signal. DS* polarity is determined by the MUX pin setting. Refer to section 21 for
details.
Signal Name:
CS*
Signal Description:
Chip Select
Signal Type:
Input
Must be low to read or write to the device. CS* is an active low signal.
Signal Name:
ALE(AS) / A7
Signal Description:
A7 or Address Latch Enable (Address Strobe)
Signal Type:
Input
In non-multiplexed bus operation (MUX = 0), serves as the upper address bit.
In multiplexed bus
operation (MUX = 1), serves to demultiplex the bus on a positive–going edge.
