TMS320F28P650DK: SYSRSn for locked protection registers

Wayne Huang
Genius 17215 points

Part Number: TMS320F28P650DK

Tool/software:

Hi champs,

I am asking this for our customer.

1. If the lock-protection is enabled for those registers, only SYSRSn can clear it. Is it right?

2. The user can use device reset including POR, watchdog reset, nXRS to reset it. Is it right?

2. If only a module wants to be unlocked, the user can use DEV_CFG_REGS.SOFTPRESx to issue a SYSRSn to reset the module and thus clear the lock registers in the module.

Is it right?

    If you are referring to any specific module ?
