14.8.3 AC Characteristics
Table 14.33 lists the control signal timing, and tables 14.34 and 14.35 list the serial interface
timing of the H8/3833 and H8/3834.
Table 14.33 Control Signal Timing of H8/3833 and H8/3834
VCC = 2.7 V to 5.5 V, AVCC = 2.7 V to 5.5 V, VSS = AVSS = 0.0 V, Ta = –20°C to +75°C, including
subactive mode, unless otherwise specified.
