NOTES :
1. This setting is enabled only for even channels. In SR waveform output mode, values written to the
corresponding odd channel (next channel after an even channel) are ignored. Even channels
provide waveform output. Odd channels provide no waveform output.
2. The inverse output function is the final step in waveform generating process. When the INV bit is set
to "1", and "H" signal is provided a default output by setting the IVL bit to "0", and an "L" signal is
provided by setting it to "1".
3. In the SR waveform output mode, set not only the even channel but also the correspoinding even
channel (next channel after the even channel).
4. To provide either "H" or "L" signal output set in the IVL bit, set the FSCj bit in the G1FS register to
"0" (select waveform generating function) and IFEj bit in the G1FE register to "1" (functions for
channel j enabled). Then set the IVL bit to "0" or "1".
