Table 5.8 Pin States in STOP Mode, Depending on the Setting of the SYSCR2.DRVE Bit
Pin Name
Pins configured for input mode and input-only pins are disabled. Pins configured for output mode and output-only
pins assume the high-Impedance state.
The input gate is active; the input voltage must be held at either the high or low level to keep the input pin from
floating.
Programmable pull-up. Because the input gate is always disabled, no overlap current flows while in high-impedance
state.
