Parallel Control Port Pins
Signal Name:
Signal Description:
Signal Type:
Flags host controller during conditions and change of states as defined in the Status Registers. Active low, open
drain output.
INT*
Interrupt
Output
Signal Name:
Signal Description:
Signal Type:
Set low to select non-multiplexed bus operation. Set high to select multiplexed bus operation.
MUX
Bus Operation
Input
Signal Name:
Signal Description:
Signal Type:
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.
D0 to D7 / AD0 to AD7
Data Bus or Address/Data Bus
Input / Output
Signal Name:
Signal Description:
Signal Type:
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.
A0 to A6
Address Bus
Input
Signal Name:
Signal Description:
Signal Type:
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
().

Input
Signal Name:
Signal Description:
Signal Type:
RD* is an active low signal. DS* polarity is determined by the MUX pin setting. Refer to section 21 for details.
RD* (DS*)
Read Input (Data Strobe)
Input
Signal Name:
Signal Description:
Signal Type:
Must be low to read or write to the device. CS* is an active low signal.
CS*
Chip Select
Input
Signal Name:
Signal Description:
Signal Type:
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.
Signal Name:
WR*( R/W*)
Signal Description:
Write Input (Read/Write)
Signal Type:
Input
WR* is an active low signal.
