3. The value given is measured at high drive strength mode. For value at low drive strength mode see the Ioh_Standard
value given above.
4. The strong pad I/O pin is capable of switching a 50 pF load at up to 40 MHz.
5. The value given is measured at high drive strength mode. For value at low drive strength mode see the Iol_Standard value
given above.
6. Several I/O have both high drive and normal drive capability selected by the associated Portx_PCRn[DSE] control bit. All
other GPIOs are normal drive only. For details refer to SK3K144_IO_Signal_Description_Input_Multiplexing.xlsx attached
with the Reference Manual.
