Appendix 3 Buffer Memory Areas
CH1 Difference conversion status flag
The difference conversion status can be checked.
When the difference conversion starts after 'CH1 Difference conversion trigger' (Un\G470) is changed from No request (0) to
Trigger request (1), 'CH1 Difference conversion status flag' (Un\G408) corresponding to the channel turns to Converting
difference (1).
When 'CH1 Difference conversion trigger' (Un\G470) is changed from Trigger request (1) to No request (0), 'CH1 Difference
conversion status flag' (Un\G408) is changed from Converting difference (1) to Not converted (0).
'CH1 Difference conversion status flag' (Un\G408) is Converting difference (1) during the difference conversion; Not
converted (0) if not during the difference conversion.
