C is the default interface (when PSEL1 and PSEL0 pins are floating or connected to VDDIO).
The I
2
C SCL and SDA pins are open drain and therefore they need pull-up resistors to VDDIO (R2
and R3 in the figure below; typical value: 2.7 k
Ω).
External components (I
2
C interface)
The MTi 1-series module acts as an I
2
C Slave. The I
2
C slave address is determined by the ADD0,
ADD1 and ADD2 pins. These pins are pulled-up internally, so when left unconnected, the address
selection defaults to ADD[0..2] = 111. The table below shows a list of all possible I
2
C addresses.
