The equation shown in Figure 3-4 must be used to configure the PLL.
IMULT is the integer value of the multiplier.
REFDIV is the reference divider for the OSCCLK.
ODIV is the output divider of the PLLRAWCLK.
PLLSYSCLKDIV is the system clock divider.
For the permissible values of the multipliers and dividers, see the documentation for the respective registers.
Many combinations of multiplier and divider can produce the same output frequency. However, the product of the reference clock frequency and the multiplier (known as the VCO frequency) must be in the range specified in the TMS320F28003x Real-Time Microcontrollers Data Sheet.
