CONTROL TIMING
(VDD = 5.0 Vdc ±10%, VSS = 0 Vdc, TA = -40°C to +85°C, unless otherwise noted)
NOTES:
1. VDD = 5.0 Vdc ± 10%, VSS = 0 Vdc, TA = TL to TH
2. The 2-bit timer prescaler 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. The minimum period tTLTL should not be less than the number of cycles it takes to execute the capture interrupt service routine
plus 24 tCYC.
