Notes
:
1.
Caution
: The SYSCLK frequency and PLL_CFG[0:4] settings must be chosen such that the
resulting SYSCLK (bus) frequency, CPU (core) frequency, and PLL (VCO) frequency do not
exceed their respective maximum or minimum operating frequencies. Refer to the
PLL_CFG[0:4] signal description in
MPC7447A RISC Microprocessor Hardware Specifications,
Section 1.9.1, “PLL Configuration,” for valid PLL_CFG[0:4] settings.
2.
Caution
: If dynamic frequency switching (DFS) is enabled, the SYSCLK frequency and
PLL_CFG[0:4] settings must be chosen such that the resulting processor frequency is greater
than or equal to the minimum core frequency.
