Notes:
1. “h” = weakly pulled “High” internally.
2. Chip Erase and Serial Programming Fuse require a 10 ms PROG pulse. Chip Erase needs to be performed first before
reprogramming any byte with a content other than FFH.
3. P3.4 is pulled Low during programming to indicate RDY/BSY.
4. “X” = don’t care
