NOTES:
7. The leakage current is measured with V
SS
or V
CC
applied to the corresponding pin(s), unless otherwise noted.
8. 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
.
9. The port pin must be selected for input and there must be no optional pullup or pulldown resistor.
