Address 0 - 14 (5 V Tolerant Inputs). These pins form the
15-bit address bus to the internal memories and registers.
A0 = LSB
Data Bus 0 - 15 (5 V Tolerant Inputs/Outputs with
Slew-Rate Control). These pins form the 16-bit data bus of
the microprocessor port.
D0 = LSB
and/or DS to initiate the next access.
port read and write operations. Note that a minimum of
30 ns must separate the de-assertion of DTA (to high) and
the assertion of CS and/or DS to initiate the next access.
Data Transfer Acknowledgment (5 V Tolerant Three-state
Output). This active LOW output indicates that a data bus
transfer is complete. A pull-up resistor is required to hold a
HIGH level. Note that a minimum of 30 ns must separate
the de-assertion of DTA (to high) and the assertion of CS
and/or DS to initiate the next access.
Chip Select (5 V Tolerant Input). Active LOW input used by
the microprocessor to enable the microprocessor port access.
Note that a minimum of 30 ns must separate the
de-assertion of DTA (to high) and the assertion of CS
Data Strobe (5 V Tolerant Input). This active LOW input
works in conjunction with CS to enable the microprocessor
Read/Write (5 V Tolerant Input). This input controls the
direction of the data bus lines (D0-D15) during a
microprocessor access.
