5.2.2
Two-Wire Serial Interface
The 98CX8234 includes a two-wire serial interface (TWSI) for each of the four port groups of
the switch. The TWSI supports master/slave transactions and multi master environments
(clock synchronization, interface arbitration). The primary use of the TWSI interface is for
switch initialization after reset, when the TWSI operates as a master for serial ROM initialization
of the switch. On ATCA-9405, the TWSI interface is not used and switch is fully configured via
Switch Management Interface.
5.2.3
Switch Management Interface
The 98CX8234 provides four PCI Express interfaces for setup, configuration, maintenance, and
management by the external SP. Each PCI Express interface is associated to one of the four port
groups of the switch. The PCI Express interfaces are connected to PEX8608 PCI Express Switch,
as listed in
