4.2.2 Signal reset states

Each interface described in this chapter includes a pin descriptions table, which
identifies each signal's reset state.
Table 4-4: Reset state definition
Parameter
0 Set to GND
1 Set to supply 1V8
Pull-down Internal pull-down with ~60 k
Pull-up Internal pull-up with ~60 k
Z High impedance
Undefined
Caution:
state is required at reset. These pins may be toggling a signal(s) during
reset.
