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.
CLAMP REGISTER 3
CR3 (CR30–CR37)
(Address (SR4–SR0) = 09H)
Figure 24 shows the various operations under the control of
Clamp Register 3.
CR3 BIT DESCRIPTION
Coarse Clamp 0 Up/Down (CR30)
This bit controls the direction of coarse clamp number 0, valid
only if the clamp is enabled.
Coarse Clamp 0 ON/OFF (CR31)
This bit switches coarse clamp number 0 on for the prescribed
number of clock cycles (CR13–CR15).
