Power-On Conditions
Example:
a) if MODE = 1, pins 28, 29 and 31 are configured as SDRAM7, SDRAM6 and SDRAM5 respectively.
b) if MODE = 0, pins 28, 29 and 31 are configured as PCI_STOP#, CPU_STOP# and PWR_DWN# respectively.
Power-On Default Conditions
At power-up and before device programming, all clocks will default to an enabled and on condition. The frequencies that are then
produced are on the FS and MODE pin as shown in the table below.
