NOTE:
The programmable logic device (PLD) addresses are calculated using offset term and the following equation:
ADDRESS = PLD_BASE + OFFSET * 80H

Memory
10.2.3.1
Program Memory, Flash
The front panel contains an ATMEL 29C512* for storing program memory and initialized vari-
ables. This device is nominally 64KB by 8 but is expandable to 128KB by 8. In order to use the
128KB by 8 devices, the memory model would need to be changed to provide enough address
space, or a paging scheme would need to be incorporated.
FRU information is not stored in this device, but, rather, is stored in the serial EEPROM.
10.2.3.2
RAM
There is 32KB by 8 of RAM on the FPC. Note that only approximately 7.5KB of the RAM is
accessible according to the memory map.
