Reserved
This read-only field is reserved and always has the value zero.
9
SCNIP
Scan-in-progress status
Indicates if a scanning process is in progress. This bit is read-only and is changed automatically by the
TSI module.
8
SWTS
Software trigger start
Setting this bit starts a scan sequence. Writing zero to this bit has no effect.
