Notes
PCI clock output buffers, pre-buffer, stop logic
Input on BUFFERIN is buffered and then output on
SDRAM[0:13]
SDRAM clock output buffers, pre-buffer, stop logic
In mobile mode (MODE = LOW), CPUCLK[0:1] tied LOW
when CPU_STOP# = LOW.
In mobile mode (MODE = LOW), PCICLK[0:4] tied LOW
when PCI_STOP# = LOW.
SDRAM clock output buffers, pre-buffer, stop logic
PLL and internal logic ground, I2C interface,
24MHz/48MHz output ground
I2C interface, 24MHz/48MHz output supply, PLL and
internal logic supply
