R
Standby Mode
The PROM enters a low-power standby mode whenever CE
is asserted High. The output remains in a high impedance
state regardless of the state of the OE input.
Programming
The devices can be programmed on programmers supplied
by Xilinx or qualified third-party vendors. The user must
ensure that the appropriate programming algorithm and the
latest version of the programmer software are used. The
wrong choice can permanently damage the device.
