4.5 Frequency output mode
4.5.1 Function
4.5.1.1 Introduction
In this operating mode, the respective channel of the technology module outputs a signal
with a fixed duty cycle of 50% and the configured On delay. You specify the frequency via
the control interface.
Starting the output sequence
In order to output the output sequence at the 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 103). The STS_SW_ENABLE feedback bit 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.
Pulse diagram
The following figure shows an example of an output sequence when DIn.0 is being used as a
hardware enable.
