1. External crystal circuit not required if using the internal clock option.
2. RESET pin can only be used to reset into user mode, you can not enter BDM using RESET pin. BDM can be entered
3. RC filter on RESET pin recommended for noisy environments.
4. For the 16-pin and 20-pin packages: V
5. When PTA4 is configured as BKGD, pin becomes bi-directional.
