14.2.3 AC Characteristics
Table 14.3 lists the control signal timing, and tables 14.4 lists the serial interface timing of the
H8/3802.
Table 14.3 Control Signal Timing
V_CC = 1.8 V to 5.5 V, AV_CC = 1.8 V to 5.5 V, V_SS = AV_SS = 0.0 V, T_a = –20°C to +75°C
(including subactive mode) unless otherwise indicated.
