PLL bypass. This bit should be set when using low bus clock frequencies (See device hardware
specifications for applicable frequencies.). When in PLL bypass mode, incoming data is captured
in the middle of the bus clock cycle.

System clock divider. Sets the frequency ratio between the system clock and the local bus clock.
The system clock is equivalent to ccb_clk . Only the values shown below are allowed. Note that
the reset value of CLKDIV depends on the boot ROM location configuration (cfg_rom_loc[0:3]).
If the FCM is selected as the boot ROM location, the default value for CLKDIV is 0100; otherwise,
the default is 1000.
Note: It is critical that no transactions are being executed via the local bus while CLKDIV is being

modified. As such, prior to modification, the user must ensure that code is not executing
out of the local bus. Once LCRR[CLKDIV] is written, the register should be read, and then
an isync should be executed.
