Functional Description
FIGURE 5-3 FLASH SIMM Connection Scheme
As can be seen in
FIGURE 5-3
, the FLASH CS is distributed to four CS signals. The distribution
depends on the size of the FLASH module installed - it is read by the BCSR using the PD(1-7) pins.

Flash Programming Voltage
Support is given to modules that require 5V for programming. The 5V voltage for programming is
taken from the main board voltage supply or 12V from external power supply in protection mode.
