Notes:
(1) VDD=3.0Vdc±10%, VSS=0Vdc, tA=tL to tH
(2) The TIMER input pin is the limiting factor in determining timer resolution.
(3) The minimum period tILIL or tIHIH should not be less than the number of cycles it takes to execute the interrupt
service routine plus 19 tCYC.
(4) Effects of processing, temperature, and supply voltage (excluding tolerances of external R and C).
