IC test data
TEST0
TEST1 All bits must be set to 0.
TEST2
All these bits are set to 0 after the power on reset.

Output port data
BO1, BO2
If deadlock occurs due to VCO oscillation when the VCO control voltage (Vtune) is 0 V, the
deadlock can be released by setting the charge pump output low and setting Vtune to V
CC
.
(This is referred to as a deadlock clear circuit.)
Determines the outputs of the SDC0 and SDC1 ports and sets the SD sensitivity.

control data
DLC
This bit should normally be set to 1. However, setting this bit to 0 sets the device to
degraded input sensitivity mode, and the input sensitivity is reduced by about 10 to
30 mV rms.
