PLL bypass. This bit should be set when using low bus clock frequencies if the PLL is unable to lock.
When in PLL bypass mode, incoming data is captured in the middle of the bus clock cycle.It is
recommended that PLL bypass mode be used at frequencies of 83 MHz or less.
0 The PLL is enabled.
1 The PLL is bypassed.

Additional external address delay cycles. Defines the number of additional cycles for the assertion of
LALE. Note that LALE negates prior to the end of the final local bus clock, as controlled by LBCR[AHD].

System (CCB) clock divider. Sets the frequency ratio between the system (CCB) clock and the memory
bus clock. Only the values shown in the table below are allowed.
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.
