Software enable: Start/enable and terminate/disable the output se-
quence.
Output disabled/terminated
Starts output sequence on positive edge when "Function DI" = "Input"
Enable output sequence, when start is dependent on HW enable with
"Function DI" = "HW enable"
Set DQn.A output source: Selects either CPU program or module's
output sequence.
DQn.A and DQn.B are controlled by the CPU (in your program) using
the SET_DQA and SET_DQB control bits.
DQn.A is controlled by the module's pulse output sequence. DQn.B is
always 0.
Controls the value of the digital output DQn.A, if TM_CTRL_DQ is
cleared.
0 on DQn.A
1 on DQn.A
Controls the value of the digital output DQn.B, if TM_CTRL_DQ is
cleared and if SET_DQA is cleared.
0 on DQn.B
1 on DQn.B
Reset pending errors (ERR_LD, ERR_DQA, ERR_DQB, and
ERR_24V).
