2.2.1 GPIO supply voltage - IOVDD
For digital communication with other circuitry (peripherals) the digital I/O configured pins
of the mixed signal sensor interface (ADIO0 to ADIO7) and the pins of the serial interface
(SCSEDIO0, SCLKDIO1, WSDADIO2, RSDADIO3) may be operated from supply voltages
different from DVDD. Therefore an interface voltage supply pin IOVDD is available which
can be connected either to DVDD or to an external supply within the tolerated voltage
range of IOVDD.

If DVDD=0 V (e.g. in any sleepmode) and IOVDD is supplied, there may be un-
predictable and varying current from IOVDD caused by internal floating nodes. It
must be taken care that the current into IOVDD does not exceed 10 mA while
DVDD=0 V.
If DVDD=0 V and IOVDD is not supplied, do not apply voltage to any above men-
tioned pin. This may lead to unpredictable malfunction of the device.
In TCM 320/TCM 320C VDD is internally connected to IOVDD! Therefore the above
mentioned issues have to be considered when writing own firmware based on API.
IOVDD voltage must not exceed VDD voltage! A malfunction of the module may be
caused by such inverse supply!
For I/O pins configured as analog pins the IOVDD voltage level is not relevant!
However it is important to connect IOVDD to a supply voltage as specified in 2.4.
