You use this bit to set digital output DQn.A when TM_CTRL_DQ and SET_DQB are set to 0.
You use this bit to set digital output DQn.B when TM_CTRL_DQ and SET_DQA are set to 0.
You enable the technological function of the digital output with this bit.
0 means: SET_DQA and SET_DQB define states of DQn.A and DQn.B
•
1 means: Output sequence defines the state of DQn.A; DQn.B is always 0.
•
You activate the software enable with this bit. If you are using the hardware enable, it is com-
bined with the software enable.
0 means: Stop output
•
1 means: Start output
•
Use of the HW enable is activated through parameter assignment. The HW enable is controlled
externally using the digital input DIn.0.
