If VCI_U2U_LOOP is set in the UI_COMN_CFG_REG, any cell received from
the UI bus, with a VCI which matches this programmed VCI, will be sent back
out to the UI bus. To avoid any momentary corruption of incoming cell data,
the value of this register should only be changed only when VCI_U2U_LOOP
in UTO_CFG_REG is disabled and UI_EN in UTO_CFG_REG s disabled.
