Flash Memory

The MVME3100 uses the LBC in General Purpose Chip Select Machine (GPCM) mode to
interface to two physical banks of on-board flash, an on-board quad UART (QUART), on-
board 32-bit timers, and the System Control/Status registers. Refer to the MVME3100
Single Board Computer Programmer's Reference Guide listed in
Documentation, for the LBC bank and chip select assignments.
4.6.1 Flash Memory
The MVME3100 provides one physical bank of soldered-on flash memory. The bank is
composed of two physical flash devices configured to operate in 16-bit mode to form a
32-bit flash bank. The default configuration for the MVME3100-1263 is 128MB using two
512Mb devices, and for the MVME3100-1152 it is 64MB using two 256Mb devices.
