SPRUIN7C March 2020 – March 2024 TMS320F280021 , TMS320F280021-Q1 , TMS320F280023 , TMS320F280023-Q1 , TMS320F280023C , TMS320F280025 , TMS320F280025-Q1 , TMS320F280025C , TMS320F280025C-Q1
The equation shown in Figure 3-4 can be used to configure the PLL.
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 TMS320F28002x Real-Time Microcontrollers Data Sheet.
