3.1.3
e600 Core to MPX/Platform Clock PLL Ratio
The clock ratio between the e600 core and the platform clock is determined by the binary value of LBCTL, LALE,
LGPL2/LOE/LFRE, DIU_LD4 (cfg_core_pll[0:3]–reset config) signals at power up. Table 58 describes the supported ratios.
Note that cfg_core_speed must be pulled low if the core frequency is 800 MHz or below.
