TMS570LS1224: Multiple PLL configuration in TMS570

Muhammed Shameel

Part Number: TMS570LS1224

Is there any restriction in TMS570 series regarding PLL configuration.  For example my use case is some part of the code ( startup bootloader routines ) shall run in a particular frequency and the rest of the functionalities shall run in another frequency.  So in the software PLL is configured to generate these frequencies 2 times at two different points in the execution.  Will this cause any issues down the line when the device gets older.

    Hi Muhammed,

    You can use 1 PLL setting for bootloader, and other different PLL setting for your application. You can also change you PLL settings even in the same application. It will not cause any issues when the device gets older.
