1. V
2. Use only AT-cut crystals.
3. Minimum oscillator frequency with RC oscillator option is limited only by size of external R and C and leakage of external C.
4. Includes processing tolerances and variations in temperature and supply voltage; excludes tolerances of external R and C.
5. The 2-bit timer prescaler is the limiting factor in determining timer resolution.
6. The minimum period, t
7. Programming time per byte is t
