7.3.2 Intel 80 Interface Timing - 3.3 Volt
S1D13742
X63A-A-001-06
When CNF1=1, MD[15:0] are used for accesses to the Memory Data Port. MD[7:0] are used for all other accesses.
Note 1: The D/C# input pin is used to distinguish between Address and Data.
Note 2: The CS# pin can be kept low between write and read pulses as the register addresses will auto-increment.
The register address will auto-increment in word increments for all register access except the Memory
Data Port. Writes to the Memory Data Port will not increment the register address to support burst data
writes to memory.
Note 3: When CNF1=0, only MD[7:0] are used.
