Each HyperTransport link supports transmit clock frequencies of 200, 400, 500, 600, 800, and 1000 MHz.
Side 0 and side 1 frequencies are independent of each other. The links can operate in asynchronous mode, as
defined in HyperTransport™ I/O Link Specification, Rev 2.0 up to a maximum of 1000 MHz receive clock
rate. On cold reset, each link begins transmitting at 200 MHz and then can be reprogrammed for higher clock
rates per HyperTransport™I/O Link Specification, Rev 2.0.
