Input-
Synchronous
Address Inputs used to select one of the 128K address locations.
Sampled at the rising edge of the CLK if ADSP or ADSC is active LOW,
and CE1, CE2, and CE3 are sampled active. A1, A0 are fed to the two-bit
counter..

Input-
Synchronous
Byte Write Select Inputs, active LOW. Qualified with BWE to conduct
byte writes to the SRAM. Sampled on the rising edge of CLK.
GW
H4
88
Input-
Synchronous
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[A:D] and BWE).
BWE
M4
87
Input-
Synchronous
Byte Write Enable Input, active LOW. Sampled on the rising edge of
CLK. This signal must be asserted LOW to conduct a byte write.
CLK
K4
89
Input-
Clock
Clock Input. Used to capture all synchronous inputs to the device. Also
used to increment the burst counter when ADV is asserted LOW, during
a burst operation.
CE1
E4
98
Input-
Synchronous
Chip Enable 1 Input, active LOW. Sampled on the rising edge of CLK.
Used in conjunction with CE2 and CE3 to select/deselect the device.
ADSP is ignored if CE1 is HIGH.
CE2
B2
97
Input-
Synchronous
Chip Enable 2 Input, active HIGH. Sampled on the rising edge of CLK.
Used in conjunction with CE1 and CE3 to select/deselect the device.
