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.

5•7•1 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.
