Bits 3 to 0: T0 DPLL Force Selected Reference (T0FORCE[3:0]). This field provides a way to force a specified
input clock to be the selected reference for the T0 DPLL. Internally this is accomplished by forcing the clock to have
the highest priority (as specified in PTAB1:REF1). In revertive mode (MCR3:REVERT = 1) the forced clock
automatically becomes the selected reference (as specified in PTAB1:SELREF) as well. In nonrevertive mode the
forced clock only becomes the selected reference when the existing selected reference is invalidated or made
unavailable for selection.
When a reference is forced, the activity monitor for that input and the T0 DPLL’s loss-of-lock timeout logic all
continue to operate and affect the relevant ISR, VALSR, and MSR register bits. However, when the reference is
declared invalid the T0 DPLL is not allowed to switch to another input clock. The T0 DPLL continues to respond to
the fast activity monitor, transitioning to mini-holdover in response to short-term events and to full holdover in
response to longer events. See Section 7.6.3.
