NOTES: 8. The leakage current is measured with VSS or VCC applied to the corresponding pins(s) – unless otherwise noted.
9. All timer/port pins (TP0.0 to TP0.5) are Hi-Z. Pins CIN and TP0.0 to TP0.5 are connected together during leakage current
measurement. In the leakage measurement mode, the input CIN is included. The input voltage is VSS or VCC.
10. The leakages of the digital port terminals are measured individually. The port terminal must be selected for input and there must
be no optional pull–up or pull–down resistor.
