Description
00Ć03
Data polarity bits. When set (1), indicate negative data. When reset (0), indicate
positive data. Bit 00 corresponds to channel 1, bit 01 to channel 2, etc.
04
When set (1), indicates negative minimum scaling value for Channel 1. When
reset (0), indicates positive minimum scaling value for channel 1.
05
When set (1), indicates negative maximum scaling value for Channel 1. When
reset (0), indicates positive maximum scaling value for channel 1.
06
When set (1), indicates negative minimum scaling value for Channel 2. When
reset (0), indicates positive minimum scaling value for channel 2.
07
When set (1), indicates negative maximum scaling value for Channel 2. When
reset (0), indicates positive maximum scaling value for channel 2.
08 (10)
When set (1), indicates negative minimum scaling value for Channel 3. When
reset (0), indicates positive minimum scaling value for channel 3.
