159 / 170 page  SECTION 17: ELECTRICAL SPECIFICATIONS Page 145 MC68HC05V7 Specification Rev. 1.0 17.8 CONTROL TIMING (VDD =3.5-4.5 Vdc ±10%, VSS = 0 Vdc, TA = -40°C to +85°C, unless otherwise noted) NOTES: 1. The 2-bit timer prescaler is the limiting factor in determining timer resolution. 2. 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. 3. 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.
