NOTES: 8. The leakage current is measured with V_SS or V_CC applied to the corresponding pin(s), unless otherwise noted.
9. All Timer/Port pins TP0.0 to TP0.5 are Hi-Z. Pins CIN and TP.0 to TP0.5 are connected together during leakage current
measurement. In the leakage measurement the input CIN is included. The input voltage is V_SS or V_CC.
10. The port pin must be selected for input and there must be no optional pullup or pulldown resistor.
11. The input voltage is V_(IN) = V_SS to V_CC , the current source is off, AEN.x bit is normally reset to stop throughput current flowing from
V_CC to V_SS terminal.
