Description
DPLL1_DPLL2_select
Bit to select between many of the registers
associated with DPLL1 or DPLL2 e.g. frequency
registers.
Not used.
cnfg_freq_lim_ph_loss
Description
freq_lim_ph_loss
Bit to enable the phase lost indication when the
DPLL hits its hard frequency limit as programmed in
Reg. 41 and Reg. 42 (cnfg_DPLL_freq_limit). This
results in the DPLL entering the phase lost state any
time the DPLL tracks to the extent of its hard limit.
Not used.
