1. V_DD = 5.0 Vdc ±10%, V_SS = 0 Vdc, T_A = T_L to T_H unless otherwise noted
2. A 2-bit prescaler in the timer is the limiting factor as it counts 4 t_CYC
3. The minimum t_TLTL should not be less than the number of interrupt service routine cycles
plus 19 t_CYC
4. The minimum t_ILIL should not be less than the number of interrupt service routine cycles
plus 19 t_CYC
