CLAMP REGISTER 2
CR2 (CR20–CR27)
(Address (SR4–SR0) = 08H)
Figure 23 shows the various operations under the control of
Clamp Register 2.
CR2 BIT DESCRIPTION
Fine Clamp 0 Up/Down (CR20)
This bit controls the direction of fine clamp number 0, valid only
if the clamp is enabled.
Fine Clamp 0 ON/OFF (CR21)
This bit switches fine clamp number 0 on for the prescribed
number of clock cycles (CR10–CR12).
Fine Clamp 1 Up/Down (CR22)
This bit controls the direction of fine clamp number 1, valid only
if the clamp is enabled.
Fine Clamp 1 ON/OFF (CR23)
This bit switches fine clamp number 1 on for the prescribed
number of clock cycles (CR10–CR12).
Fine Clamp 2 Up/Down (CR24)
This bit controls the direction of fine clamp number 2, valid only
if the clamp is enabled.
Fine Clamp 2 ON/OFF (CR25)
This bit switches fine clamp number 2 on for the prescribed
number of clock cycles (CR10–CR12).
Reserved (CR26–CR27)
Zero must be written to these registers.
