STLUX385A

Product overview

The SMED units may be configured in different coupled schemes through the

SMDx_GLBCONF and SMDx_DRVOUT bit fields of MSC_SMEDCFGxy registers.

An outline of SMED subsystem is shown in

Figure 3.

Connection matrix

The connection matrix extends the input connectivity of each SMED unit so that a SMED

can receive events from a wide range of sources. Through the matrix, it's possible to

connect the SMED inputs to various signal families such as digital inputs, comparator output

signals, SW events, and three PWM internal feedback signals as shown in

Figure 4.

The list of the available event sources is the following:

•

DIGIN(5:0) digital input lines

•

CMP(3:0) analog comparator outputs

•

PWM(5:0) output signals of SMEDs (only PWM 0, 1 and 5 are accessible)

•

SW(5:0) software events
