This bit determines whether the T0/T4 DPLL in hard alarm status will result in it unlocked.
0: Disabled.
1: Enabled. (default)
These bits represent an unsigned integer. If the value is multiplied by 0.724, the DPLL soft limit for T0 and T4 paths in
ppm will be gotten.
The DPLL soft limit is symmetrical about zero.
The CURRENT_DPLL_FREQ[23:0] bits represent a 2’s complement signed integer. If the value in these bits is mul-
tiplied by 0.000011, the current frequency offset of the T0/T4 DPLL output in ppm with respect to the master clock
will be gotten.
