1. These bits may be written, but will have no effect on the device.
2. This bit is not available on this device and is thus reserved.
Field
Overwrite enable
This bit enables or disables the functionality to overwrite unread converted data in ICDR, TCDR,
0
ECDR registers.
OWREN
0 Prevents overwrite of unread converted data, new result is discarded
1 Enables converted data to be overwritten by a new conversion
Write left/right-aligned
1
0 The conversion data in ICDR, TCDR, ECDR registers is written right-aligned.
WLSIDE
1 Conversion data is left-aligned (from 15 to (15 – resolution + 1)).
One Shot/Scan
2
0 One Shot Mode—Configures the normal conversion of one chain.
MODE 1 Scan Mode—Configures continuous chain conversion mode; when the programmed chain
conversion is finished it restarts immediately.
3 Reserved
Normal Start conversion
Setting this bit starts the chain or scan conversion. Resetting this bit during scan mode causes
4
the current chain conversion to finish, then stops the operation.
NSTART
0 Causes the current chain conversion to finish and stops the operation
1 Starts the chain or scan conversion
Normal trigger enable
5
0 Normal trigger disabled to start a normal conversion.
NTRGEN
1 Normal trigger enabled to start a normal conversion.
