Notes
SWMODE[3:0]
Switch Mode.
These configuration pins determine the PES64H16 switch operating mode.
Default: 0x0
0x0 - Normal switch mode
0x1 - Normal switch mode with Serial EEPROM-based initialization
0x2 through 0x7 - Reserved
0x8 - Normal switch mode with upstream port failover (port 0 selected as the upstream port)
0x9 - Normal switch mode with upstream port failover (port 2 selected as the upstream port)
0xA - Normal switch mode with Serial EEPROM and upstream port failover (port 0 selected
as the upstream port)
0xB - Normal switch mode with Serial EEPROM and upstream port failover (port 2 selected
as the upstream port)
0xC through 0xF - Reserved
REFCLKM
PCI Express Reference Clock Mode Select
. This signal selects the frequency of the ref-
erence clock input.
Default: 0x0
0x0 - 100 MHz
0x1 - 125 MHz
MSMBADDR[4:1]
Master SMBus Address.
These pins determine the SMBus address of the serial EEPROM
from which configuration information is loaded.
Default: 0x0
