+As of the wirering of MODA and MODB pins, the chip is running in "Normal Single Chip Mode". This means:
-^ MODA ^ MODB ^ Program Flash secured ^ Chip mode ^ Description ^
+  - All debug features available (JTAG, for example)
-|  0  |  0  |  No  | Normal Single-Chip Mode | Boots from internal flash |
