Notes:
1. Not including any current drawn from the device pins by external circuitry.
2. At VDD = 5.0V only. Signal levels are proportional to VDD, driven with a source
impedance of <1000Ω.
3. 2-tone mode covers tones from ROM Page 1 and 2; 5/6-tone and HSC mode covers tones
from ROM Page 3. Desponse times are for 95% probability.
4. Timing for an external input to the XTAL/CLOCK pin.
