ComparePointer shows the buffer number where a comparison is made now.
When all the comparison is complete and the next buffer is empty, the last comparison output will be
retained.
You can determine whether the comparison is complete by checking that ComparePointer is the same
as TableWritePointer.
Setting CompareEnable to 0 will stop the comparison and reset the comparison output to 0.
Then, setting CompareEnable to 1 will start a comparison again from Comparetable[0].
Setting of Comparison Output
CompOutPol(Gate3[i].Chan[2].CompB[25]) sets the polarity of a comparison output.
For CompOutPol = 0, OUT1 outputs 5 V with a comparison output = 1.
For CompOutPol = 1, OUT1 outputs 0 V with a comparison output = 1.
You can forcibly set a comparison output by using CompOutWrite (Gate3[i].Chan[2].CompB[27:26]).
This is a 2-bit register, where the lower bit is write enable and the higher bit is the preset value of a
CompOut signal.
CompOutWrite is always enabled regardless of CompareEnable.
CompOut (Gate3[i].Chan[3].CompB [31]) allows you to check the status of a comparison output.
The following shows examples of operation of the TCR output function.
