Bit 5: T0 DPLL Frequency Soft Alarm (T0SOFT). This real-time status bit indicates whether the T0 DPLL is
tracking its reference within the soft alarm limits specified in the SOFT[6:0] field of the
Section 7.7.5.
Bits 2 to 0: T0 DPLL Operating State (T0STATE[2:0]). This real-time status field indicates the current state of the
T0 DPLL state machine. Values not listed below correspond to invalid (unused) states. See Section 7.7.1.

Bits 3 to 0: Selected Reference (SELREF[3:0]). This real-time status field indicates the current selected
reference for the T0 DPLL. The default value for this field is 0011b if the SRCSW pin is 1 during reset and 0100b if
SRCSW is 0 during reset.
