The T-SMINT
applications where no controller is connected to the T-SMINT
interface, register programming is done via the IOM
master device. In such applications the T-SMINT

The interface selections are all done by pinstrapping. The possible interface selections
are listed in
released. For the pin levels stated in the tables the following is defined:
’High’:dynamic pin value which must be ’High’ when the pin level is evaluated

Note: For a selected interface mode which does not require all pins (e.g. address pins)
The microcontroller interface also consists of a microcontroller clock generation at pin
MCLK, an interrupt request at pin INT, a reset input pin RST and a reset output pin
RSTO.
The interrupt request pin INT (open drain output) becomes active if the T-SMINT
requests an interrupt.
2.1.1
The serial control interface (SCI) is compatible to the SPI interface of Motorola and to the
Siemens C510 family of microcontrollers.
The SCI consists of 4 lines: SCLK, SDX, SDR and CS. Data is transferred via the lines
SDR and SDX at the rate given by SCLK. The falling edge of CS indicates the beginning
