The CLKIN frequency, RCWL[SPMF], and RCWL[COREPLL] settings must be chosen so that the resulting csb_clk, MCK,
LCLK[0:2], and core_clk frequencies do not exceed their respective maximum or minimum operating frequencies. The value of
SCCR[ENCCM], SCCR[USBDRCM] and SCCR[USBMPHCM] must be programmed so that the maximum internal operating
frequency of the security core and USB modules does not exceed the respective values listed in this table.
The DDR data rate is 2x the DDR memory bus frequency.
The DDR data rate is 2x the DDR memory bus frequency.
The local bus frequency is 1/2, 1/4, or 1/8 of the lbiu_clk frequency (depending on LCCR[CLKDIV]) which is in turn 1x or 2x the
csb_clk frequency (depending on RCWL[LBIUCM]).
