Address inputs used to select one of the 128 K address locations. Sampled at the rising edge
of the CLK if ADSP or ADSC is active LOW, and CE
the 2-bit counter.
Byte write select inputs, active LOW. Qualified with BWE to conduct byte writes to the SRAM.
Sampled on the rising edge of CLK.
Global write enable input, active LOW. When asserted LOW on the rising edge of CLK, a global
write is conducted (all bytes are written, regardless of the values on BW

Output enable, asynchronous input, active LOW. Controls the direction of the I/O pins. When
LOW, the I/O pins behave as outputs. When deasserted HIGH, I/O pins are tri-stated, and act as
input data pins. OE is masked during the first clock of a read cycle when emerging from a deselected
state.
