ADCRCLK_Inv

ADCRCLK Invert.

This bit inverts the ADCRCLK signal.

• 0 = Do not invert the ADCRCLK signal.

• 1 = Invert the ADCRCLK signal (default).

37:6-

37:5

ADCRCLK_Del

ADCRCLK Delay.

These bits delay the ADCRCLK signal, relative to data, in

0.5-ns increments.

• 0 = 0-ns delay of ADCRCLK

• 1 = 0.5-ns delay of ADCRCLK

• 2 = 1.0-ns delay of ADCRCLK (default)

• 3 = 1.5-ns delay of ADCRCLK

Reserved

Reserved.

• See Section 6.1, “Reserved Bits”.

• This bit must be programmed to ‘0’.

37:3

Cal_Access

Calibration Access.

Depending on the state of the VSS(TEST) pin (see

Section 3.2.3.6, “Ground Pins”), this bit performs in either

the Normal mode or the Test mode.

• Normal mode.

When the ICS1531 is in Normal mode and this bit =

– 0, Calibration Regs cannot be accessed.

– 1, Calibration Regs 38h to 3Ch can be accessed.

• Test mode.

– When the ICS1531 is in Test mode, Calibration

Regs 38h to 3Ch can be accessed, regardless of

the setting of Reg 37:3.

– The Test mode is intended for use only by ICS.
