7.13.15

SETTCOEFFCHN (0x53)

Set temperature coefficient in the specified channel.

Contains 40 bits payload: 3x8 bits temperature coefficient, 8 bits temperature reference and

8 bits for channel selection (note that on SAID, having only 3 channels, only 2 bits are used for

channel selection using values from 0 to 2).

No answer (16-bit TEMPSTAT register if SR bit is set).
