Bidirectional Data Port A. Usually connected to the CPU's Address/Data bus.
Bidirectional Data Port 1B. Connected to the even path or even bank of memory.
Bidirectional Data Port 2B. Connected to the odd path or odd bank of memory.
Latch Enable Input for A-1B Latch. The Latch is open when LEA1B is HIGH. Data from the A-port is latched on the HIGH to LOW
transition of LEA1B.
Latch Enable Input for A-2B Latch. The Latch is open when LEA2B is HIGH. Data from the A-Port is latched on the HIGH to LOW
transition of LEA2B.
Latch Enable Input for 1B-A Latch. The Latch is open when LE1B is HIGH. Data from the 1B-Port is latched on the HIGH to LOW
transition of LE1B
Latch Enable Input for 2B-A Latch. The Latch is open when LE2B is HIGH. Data from the A-Port is latched on the HIGH to LOW
transition of LE2B.
1B or 2B Path Selection. When HIGH, SEL enables data transfer from 1B Port to A Port. When LOW, SEL enables data
transfer from 2B Port to A Port.
Output Enable for A Port (Active LOW).
Output Enable for 1B Port (Active LOW).
Output Enable for 2B Port (Active LOW).
