REGISTER 1 MAPPING
Data Field
DB31
FULL_CAL_REQ
This is a read only bit, that indicates if a
0 power-up cal is not required
power-up cal is required
1 power-up cal is required
DB30
CP_TEST
TI internal use only
1 test enabled
DB29
TRIS_CP
High-impedance state charge pump
1 CP high-impedance state
output
0 for normal operation
DB28
PFD_POL
Selects Polarity of PFD, should match
0 negative
polarity of VCO gain. If using external
1 positive
VCO with Negative gain then set to 0
and vise versa. The internal VCO has
positive gain so set to positve(1)
