Notes: *1 Even when the A/D and D/A converters are not used, connect AV_CC to power supply V_CC
and keep the applied voltage between 2.0 V and 5.5 V. At this time, make sure AV_ref ≤
AV_CC.
*2 Current dissipation values assume that V_{IH min} = V_CC – 0.5 V, V_CCB – 0.5 V, V_{IL max} = 0.5 V,
all output pins are in the no-load state, and all input pull-up transistors are off.
*3 For these values it is assumed that V_RAM ≤ V_CC < 4.5 V and V_{IH min} = V_CC × 0.9,
V_CCB × 0.9, V_{IL max} = 0.3 V.
*4 P6₇ to P6₀ include supporting module inputs multiplexed with them.
*5 IRQ₂ includes ADTRG multiplexed with it.
*6 Applies when IICS = IICE = 0. The output low level is determined separately when the
bus drive function is selected.
*7 The characteristics of PA₇ to PA₄, KEYIN₁₅ to KEYIN₁₂, P9₇/WAIT, SDA, and
P8₆/IRQ₅/SCK₁, SCL depend on V_CCB; the characteristics of all other pins depend on
V_CC.
