TMS570LC4357: Default states of each power domain.

Andrew Harrington

I have a question on the default power domain states of the Hercules TMS570LC4x.

I am using the TMS570LC4357 and section 5.3.2 Default Power Domain State for the Power Management Module (PMM) in the Technical Reference Manual TMS570LC43x 16/32-Bit RISC Flash Microcontroller (SPNU563A March 2018) states that "The default state of each power domain, except for PD1, is controlled by TI during production testing via programmation of individual bits within the reset configuration word in the TI-OTP sector of flash bank 0."

The OTP Memory is described in section 7.5.2, but the default state of each power domain is not defined.

What are the default states of each power domain?

Hi Andrew,

You are correct about this default power domain states, yes this info is missing in TRM. I even searched in old threads and i don't find anything related to this. So, now i would like to discuss this with my internal team and i will get back to you, as soon as i got response from them.

Thanks,

Jagadish.
