Switching Waveforms
Architecture Configuration Bits
The CY7C276 has four user-programmable options in addition
to the reprogrammable data array. For detailed programming
information contact your local Cypress representative.
The programmable options determine the active polarity for
the three chip selects (CS2 - CS0) and OE. When these con-
trol bits are programmed with a 0 the inputs are active LOW.
When these control bits are programmed with a 1 the inputs
are active HIGH.
