8.14 Difference Conversion Function
(b) Operation when Initial data setting request flag (RY9) is switched
• During difference conversion, turning on and off Initial data setting request flag (RY9) results in the
difference conversion continuing without updating the difference conversion reference value. At this time,
even if the digital clipping function, scaling function, and shift function are set valid, the difference
conversion reference value is not updated. To update the difference conversion reference value, change
CH Difference conversion trigger (RY14 to RY17, RY24 to RY27) as follows: Trigger request (ON)→No
request (OFF)→Trigger request (ON).
• Before CH A/D conversion completed flag (RX10 to RX13, RX20 to RX23) turns on from off by turning
on Initial data setting request flag (RY9) from off, changing CH Difference conversion trigger (RY14 to
RY17, RY24 to RY27) from No request (OFF) to Trigger request (ON) results in operation with the
difference conversion reference value taking on the digital operation value at the time when CH A/D
conversion completed flag (RX10 to RX13, RX20 to RX23) turns on from off.
