MSP432P401M: Delay for RST deassertion duing power up

Oba

Part Number: MSP432P401M

Hello

I have a question about RST pin input of MSP430P401M,
I think MCU usually requires some delay for RST deassertion during/after power-up like the below which is from C2000 MCU(!XRS is Reset input in this case).

Doesn’t MSP432 require this kind of delay for RST deassertion?
I could not find any information like that in the datasheet.

Hi Oba,

I didn't find anything in the datasheet relating to this. I don't believe there is such a requirement for the MSP432P4. I would just recommend being mindful of the reset timing latencies outlined in section 5.25.1 of the datasheet.

Thanks,

Alexis

Hello Alexis,

Thanks for your reply.

Could you pleases make clear why this kind of requirement for external reset signal is not required?
Because internal reset completely takes care of POR timing whenever external reset is de-asserted?

Hi Oba,

I found the following in the Technical Reference Manual.

You can refer to Section 7.2 for more information on the device power-up: http://www.ti.com/lit/ug/slau356h/slau356h.pdf

Thanks,

Alexis
