MSP430F5419A: Adding an external reset source

Hello,

My customer would like to add an external reset signal to F5419A.

At the same time the board needs a Spy-Bi-Wire debug capability.

Then I would think the circuit is good, but do you have any suggestions or concerns ?

My points are:

  • The base is the SBW circuit in the SLAU278Y, p24.
  • The external reset source should be open-collector or open-drain.

 

I copied the external reset source circuit from MSP-EXP430F5529:
