DDR memory bus frequency (MCLK)
Local bus frequency (LCLK n )
PCI input frequency (CLKIN or PCI_CLK)
Security core maximum internal operating frequency
USB_DR, USB_MPH maximum internal operating
frequency
The CLKIN frequency, RCWL[SPMF], and RCWL[COREPLL] settings must be chosen so that the resulting csb_clk , MCLK,
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 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]).
