Cal_EN

000

[7:3] CSInterval

Set the interval between samples in one calibration unit

Interval = CSInterval[4:0]*10ms

[2:1] IModel

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

[0] Cal_EN

‘1’ to enable the auto-calibration

‘0’ to disable the auto-calibration
