TMS320F28377D: Inquiries about the SYSRSn method

LEE Jea kyung

Part Number: TMS320F28377D

Hello

I have a question about 28377D Reset.

I know SYSRSN is a system reset, but I'm curious how it works.

Do I need to initialize the DSP chip itself?
(POWER ON/OFF or CCS Reset etc...)
Or is there an initialization code that I just need to input?

please answer about my question.

    Page 95 of www.ti.com/lit/SPRUHM8 explains the resources that are affected by -SYSRS and resources that are not. Any module that is impacted by -SYSRS must be reinitialized.

     

    "CPU1's subsystem reset (CPU1.SYSRS) resets CPU1, its peripherals, many

    system control registers (including its clock gating and LPM configuration and the peripherals' CPU

    ownership), and all I/O pin configurations. It also produces a CPU2.SYSRS and holds CPU2 in reset. 

    Neither SYSRS resets the ICEPick debug module, the device capability registers, the clock source and

    PLL configurations, the missing clock detection state, the PIE vector fetch error handler address, the NMI

    flags, the analog trims, or anything reset only by a POR"
