SwRst
[31]
Camera interface software reset. Before setting this bit, you
should set the ITU601_656n bit of CISRCFMT as “1”
temporarily at first SFR setting. Next sequence is
recommended.
(ITU601 case : ITU601_656n “1”
→
SwRst “1”
→
SwRst “0”
for first SFR setting ,
ITU656 case : ITU601_656n “1”
→
SwRst “1”
→
SwRst “0”
→
ITU601_656n “0” for first SFR setting)
