REGISTER DESCRIPTION (Cont’d)
CONTROL LOGIC REGISTER 1 (CLR1)
R252 - Read/Write
Register Page: 63
Reset Value: 0000 1111 (0Fh)
Bits 7:4 = SC[3:0]: Start Conversion Channel
These four bits define the starting analog input
channel (Autoscan Mode). The first channel ad-
dressed by SC[3:0] is converted, then the channel
number is incremented for the successive conver-
sion, until channel 15 (1111) is converted. When
SC3, SC2, SC1 and SC0 are all set, only channel
15 will be converted.
Bits 3:0 = CC[3:0]: Compare Channels
The programmed value corresponds to the first of
the two adjacent channels (A) on which it is possi-
ble to define a level window for the converted ana-
log input (see
Note: If a write access to this register occurs, the
conversion is re-started from the SC[3:0] channel.
