Notes
RSTHALT
Reset Halt.
When this signal is asserted during a PCI Express fundamental reset, the
PES12N3 executes the reset procedure and remains in a reset state with the Master
and Slave SMBuses active. This allows software to read and write registers internal to
the device before normal device operation begins. The device exits the reset state
when the RSTHALT bit is cleared in the PA_SWCTL register through the SMBus.
The value may be overridden by modifying the RSTHALT bit in the PA_SWCTL regis-
ter.
Default: 0x0
SWMODE[3:0]
Switch Mode.
These configuration pins determine the PES12N3 switch operating
mode.
Default
1
: 0x0
0x0 - Initialization without serial EEPROM
0x1 - Serial EEPROM-based initialization
0x2 through 0x5 - Reserved
0x6 - Scan test mode (factory use only)
0x7 - PLL Bypass test mode
0x8 - 10-bit loop-back test mode
0x9 - Reserved
0xA - Internal pseudo random bit stream self-test mode
0xB - External pseudo random bit stream self-test mode
0xC - Reserved
0xD - SerDes broadcast test mode
0xE - Reserved
0xF - Reserved
1.
The default setting is 0x1 if the PES12N3A device is on the board.
