I'm trying to figure out the debugger interface on a Freescale MCU. The chip is driven by this 5 volt regulator.
https://www.st.com/resource/en/datasheet/l5300ah7.pdf
Pin 3 is a reset output. It goes to the reset pin on the MCU with nothing but a zero ohm jumper in between.
Per the regulator data sheet, reset output is internally connected to 5 volt output through a 20 K-ohm pull up resistor.
So my dumb question is, if I connect my debugger to that reset circuit, will I fry something when the debugger pulls reset low?
I could pull the zero ohm jumper off, but that thing is tiny and I don't want to risk damaging the board taking it on and off.
Potentially stupid question about pull-up resistor and reset circuit
