Set the interval between samples in one calibration unit
Interval = CSInterval[4:0]*10mS
Set the calibration model
‘00’ for normal auto-calibration
‘10’ for auto-calibration with auto-tuning. In this mode channel reference delay is not accessible
from I2C. The system will perform auto-tuning if the impedance is moving out of dynamic range.
‘01’ is reserved
‘11’ is reserved
‘1’ to enable the auto-calibration
‘0’ to disable the auto-calibration
