4.10 SPI Flash

There are two SPI flash headers.

The chips can be accessed through a 2x4-pin SP100 header, either by chipset or external
devices with SPI interface .

When using the SF100 on board program function, the AC power of the system should be fully
cut to avoid damage to the module. A 3-pin jumper (P46) is supplied to configure which SPI
flash will be programmed. The chip select signal from the Module CS0# is routed to the U9 and
the CS1# is routed to the U10. For information on pin assignments, see

Table "P46, SPI Flash

Configuration" on page 50
