∗1 The PE to PF show when the combined pins are selected as the port, and SEG16 to SEG23 show when
the combined pins are selected as the segment output.
∗2 It is when the respective pins of PA to PF and PX0 to PX2 select the 3-state output circuit, and PY0 and
PY1 are when the inverter output circuit is selected.
∗3 It is when the respective pins of PA to PF, PX0 to PX2, PY0 and PY1 select the pull-up resistance.
∗4 It is when the crystal or ceramic oscillation circuit is selected.
∗5 The RST pin specifies the input current when the pull-up resistance is selected, and specifies leakage
current when non-resistance is selected.
∗6 The respective pins of PA to PF and PX0 to PX2 specify the input current when the pull-up resistance is
selected, and specify the leakage current when in the port state during the 3-state output circuit or standby
is selected at high impedance.
∗7 The respective pins of PY0 and PY1 specify the input current when the pull-up resistance is selected, and
specify the leakage current when in the port state during standby is selected at high impedance.
∗8 The respective pins of PX3, PY2, PY3, INT1 and WP only specify the leakage current.
