1. +3.0 ≤ V_DD ≤ +5.5 Vdc, V_SS = 0 Vdc,T_L ≤ T_A ≤ T_H, unless otherwise noted.
2. The system clock divider configuration (SYS1–SYS0 bits) should be selected such that the internal operating frequency
(f_OP) does not exceed value specified in f_OP for a given f_OSC.
3. The minimum period, t_ILIL, should not be less than the number of cycle times it takes to execute the interrupt service routine
plus 21 t_cyc.
