SDA and SCL are internally pulled up with each 1 kΩ resistor to voltage 2.8V (VREF)
inside the Q64 Wireless CPU

.
The reset states for each I/O are given in the corresponding interface chapter
descriptions. The state definitions are defined below:
Reset state definition
Parameter Definition
0
Set to GND
1
Set to supply 2V8
Pull down
Internal pull down with ~60K resistor.
Pull up Internal pull up with ~60K resistor to supply 2V8.
Z High impedance
Undefined Be careful, undefined should not be used in your application
if a special state is needed at reset. Those pins can be
toggling signals during reset.
