9.3 Interconnect registers (per node)
The following registers are in the interconnect - they can be accessed over JTAG
or by sending a message to the system switch. The message is specified in
Section 3.6.2. Changing these registers has a global effect on the chip.

PLL control register.
Lowest 16 bits set the switch clock frequency, clk = pll (n + 1). Keep
at 0 for 400 MHz.
Lowest 16 bits define the relation between the reference clock and
the PLL clock, ref = pll (n + 1). Keep at 3 for 100 MHz.
