XC4000E: What is state of RAMs upon power-up/configuration?


RAMs (as well as ROMs) are initialized at power-up of the device
in the xc4000E devices.

By default, all RAM/ROM contents are initialized to all zeros.
The initialization values may be defined by the user by attaching
an INIT attribute to the RAM (or ROM) symbol:
where value is the hexidecimal initialization value.

Note that RAM initialization occurs only during configuration.
RAM content is not affected by the Global Set/Reset.
