USER MANUAL
STM 300 / STM 300C
2.3.1 GPIO supply voltage
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 programming
interface (SCSEDIO0, SCLKDIO1, WSDADIO2, RSDADIO3) may be operated from supply
voltages different from DVDD. Therefore an interface supply voltage pin IOVDD is available
which can be connected either to DVDD or to an external supply within the tolerated volt-
age range of IOVDD. Please note that the wristwatch XTAL I/Os WXIDIO and WXODIO are
always supplied from UVDD.

Polarity can be inverted, delay time can be
programmed, see 2.8.2.

See 2.7 for description of behaviour.
Change of logic state leads to wake-up and
transmission of a telegram. See also 3.3.
Change of logic state to LOW leads to
wake-up and transmission of teach-in tele-
gram if a manufacturer code is pro-
grammed. See also 2.9.2 and 3.3.
