Clocking
Binary value on LA[28:31] at power up
Note that there is no default for this PLL ratio; these signals must be pulled to the desired values. Also note
that the DDR data rate is the determining factor in selecting the MPX bus frequency because the MPX
frequency must equal the DDR data rate.
18.3
e600 to MPX clock PLL Ratio
Table 69 describes the clock ratio between the platform and the e600 core clock. This ratio is determined
by the binary value of LDP[0:3], LA[27](cfg_core_pll[0:4] - reset config name) at power up, as shown in
18.4
