MSP430FR5858: What is the state of GPIO when the device is in reset state.

Expert 2805 points
Part Number: MSP430FR5858

Hi,

My customer wants to know the state of the pin during reset(i.e. the nRST/NMI pin is held low).

It seems that  that the pins will be in their default state (inputs).

1.Is my understanding correct?

I found the following thread: 

https://e2e.ti.com/support/microcontrollers/msp430/f/166/p/439732/1578842#1578842

In addition, I tried to check the following contents, but I could not.

http://processors.wiki.ti.com/index.php/MSP430_FAQ#What_is_the_state_of_GPIO_when_the_device_is_in_reset_state.3F

2.Is this FAQ in a different location?

Best regards,

O.H

  • Hi O.H,

    1. A reset will trigger BOR. After a BOR reset, all port pins are high-impedance with Schmitt triggers and their module functions disabled to prevent any cross currents. See section 1.2 and 12.3 for more information.

    2. All wiki pages are not available. We are considering port this document to a new location.
