Hey guys, just wanted to know if someone knows the minimum rise time required for the HVPP when the AVR is using:

1. Default internal clock, and

2. fast SUT

 

in reference, 10uS rise time seems to be okay and the HVPP is entered correctly.

 

thanks a lot for any inputs.

It does not seem that the ds is concerned with the 12v rise time, only the vcc rise to 1.8v or greater.

Since the only time HVPP is required is when RSTDISBL fuse has been messed with, best to not mess with it in the first place.

Top Tips:

  1. How to properly post source code - see: https://www.avrfreaks.net/comment... - also how to properly include images/pictures
  2. "Garbage" characters on a serial terminal are (almost?) invariably due to wrong baud rate - see: https://learn.sparkfun.com/tutorials/serial-communication
  3. Wrong baud rate is usually due to not running at the speed you thought; check by blinking a LED to see if you get the speed you expected
