TMS320F280025: lock VREG

Part Number: TMS320F280025
Other Parts Discussed in Thread: C2000WARE

Hello Champs,

In F28002x example projects in the latest C2000ware, at the end of the "Device_init()" function, there is below operation for locking the VREGCTL register: 

//

// Lock VREGCTL Register

// The register VREGCTL is not supported in this device. It is locked to

// prevent any writes to this register

//

ASysCtl_lockVREG();

Would you please kindly suggest whether it's necessary or not? What about the purpose for adding this function? Thanks!

Best Regards,

Linda
