Mode 1: The GL9714 is configured into an x4 lane, 8-bit parallel bus and acts as a 4-lane PCI Express PHY.
The parallel bus is synchronous with PCLK at 250 MHz. By transitioning both TXCMPx and
TXIDLEx to high for individual lane, the GL9714 in this mode is able to behave as an x1 or x2 PHY.
Mode 2: The GL9714 acts as a 2-lane PHY with a 16-bit parallel interface at 125 MHz. In this mode, only
lane B and lane C are activated. Again, by disabling either lane using TXCMPx and TXIDLEx,
the GL9714 can be configured into an x1 PHY with16-bit parallel bus.
Mode 3: The GL9714 is configured as a quad SerDes with 10-bit parallel bus.
Mode 4: For scan test only
