6.19
Setting Error Flag [BFM #38]
BFM Access : Read / Write (Valid Value : 0 bitwise)
This BFM shows the setting error reasons. This BFM corresponds to BFM#29 Bit6. By resetting BFM#29 Bit6,
BFM#38 also resets. By writing 0 to each bit in BFM#38, each flag resets individually.
*1.
If writing "0" to BFM#1298 when the 32DP is not in data exchange mode, the 32DP keeps BFM#1309
- #1322 contents, whereas the 32DP clears them at the next mode switch into data exchange mode.
