Table 3.6 shows a list of the I/O signals for the D/A converter modules.
The following explanation is mentioned based on the Q68DAVN, Q68DAIN, Q68DAV
and Q68DAI with 8-channel analog output (CH1 to CH8).
Note that I/O numbers (X/Y) shown in this chapter and thereafter are the values when
the start I/O number for the D/A converter module is set to 0.
