im trying to prog r5f6411flng with usb-rs232 converter(in pictures i added) and renesas programming software.
i find all pinouts and i tried to make all connections up to datasheet, but im not still succesfull.
i made all connections as datasheet
i used 2.2k ohm to vcc to power nmi , cnvss,ce.because i coudnt find any value at datasheet
device originally powered with 3.3v also u tried 5v to. when i applied 5v nmi , cnvss, ,ce voltage changed to3.3 volt.
where i am making wrong?
VCC is 3.3
and i measured while connected to programmer
RESET- NOT CONNECTED (I CUT LINE AT PBC)
