FX2N-8AD Analog input block Buffer Memory (BFM) 8
8-18
8.2.6 BFM #21: Writes I/O characteristics
Each channel No. is assigned to the lower eight bits of BFM #21.
When a bit is set to ON, the offset data (BFM #41 to BFM #48) and the gain data (BFM #51 to
BFM #58) of the assigned channel No. are written to the built-in memory (EEPROM), and
become valid.
You can give the write command to two or more channels at a time. (When you input "HFF", all
channels are written.)
When write is completed, BFM #21 returns automatically to K0.
