Must be set to 0 except when in the AUX-EN test mode.
M counter control bits. Modulus = value + 1.
DESCRIPTION
Must be set to 0.
PCLK output.
Must be set to 0.
Sets the gain of VCO
Must be set to 1.
Sets the gain of the phase detector according to this table:
Must be set to 0.
Phase detector tuning bit. Should normally be set to one.
When = 0, PCLK output enabled when PCLKEN input is
low. When = 1, PCLK output enabled when PCLKEN input
is high.
Controls A counter. When set to zero, modulus = 7.
Otherwise, modulus = 7 for "value" underflows of the
prescaler, and modulus = 6 thereafter until M counter
underflows.
Doubles modulus of dual-modulus prescaler (from 6 / 7 to
