This bit determines whether the T0 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 path in ppm will
be gotten.
The DPLL soft limit is symmetrical about zero.

The DPLL_FREQ_HARD_LIMT[15:0] bits represent an unsigned integer. If the value is multiplied by 0.0014, the
DPLL hard limit for T0 path in ppm will be gotten.
The DPLL hard limit is symmetrical about zero.
