The reset states of the I/Os are given in each interface description chapter.
Definitions of these states are given below:
Reset state definition
Parameter Definition
0
Set to GND
1
Set to supply 1V8 or 2V8 depending on I/O type
Pull-down
Internal pull-down with ~60k
Ω
resistor.
Pull-up Internal pull-up with ~60k
Ω
resistor to supply 1V8 or 2V8
depending on I/O type.
Z High impedance
Undefined Caution: undefined must not be used in your application if a
special state is required at reset. These pins may be a
toggling signal during reset.
