If TM2 is strapped to high, PI7C9X130 uses TM1, TM0, and MSK_IN as strapping pins. The strapping
functions are listed in Table 3-2 to show the states of operations during the PCI Express PERST_L de-
assertion transition in forward bridge mode or PCI RESET_L de-assertion transition in reverse bridge
mode.
