CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (SVD Circuit)
4.13.5 Programming notes
(1) To obtain a stable detection result, the SVD circuit must be ON for at least l00 µsec. So, to obtain the
SVD detection result, follow the programming sequence below.
1. Set SVDON to "1"
2. Maintain for 100 µsec minimum
3. Set SVDON to "0"
4. Read SVDDT
(2) The SVD circuit should normally be turned OFF because SVD operation increase current consump-
tion.
