Function

4.2.1.1

Introduction

In this operating mode, the respective channel of the technology module outputs a pulse
width modulated signal with the configured minimum pulse duration and the configured
period duration. You can superimpose a dither signal on the PWM signal. The module also
has an integrated PID controller that can be used to control the output current.
You specify the duty cycle or current setpoint via the control interface.

Output sequence

Starting the output sequence
In order to output the output sequence at digital output DQn.A, the TM_CTRL_DQ control bit
(Page 126) must be set. To start the output sequence using the software enable, you set the
SW_ENABLE control bit (Page 55). The STS_SW_ENABLE feedback bit (Page 58) indicates
that the software enable in the technology module is active.
You can additionally use the hardware enable via the respective digital input DIn.0. You can
configure an input delay for DIn.0.
