Bit 7: Lock T4 to T0 (LKT4T0). When this bit is set to 1 (and T0CR1:T4APT0 = 0) all output clocks are generated
from the T0 DPLL, and the T4CR1:T4FREQ field selects the frequency of the T4 APLL. See Section 7.8.2.2. When
LKT4T0 = 0, the T4 APLL can be locked to either the T4 DPLL or the T0 DPLL depending on the setting of
T0CR1:T4APT0.
Bits 3 to 0: T4 DPL Force Selected Reference (T4FORCE[3:0]). This field provides a way to force a specified
input clock to be the selected reference for the T4 DPLL. Internally this is accomplished by forcing the clock to have
the highest priority (as specified in PTAB1:REF1). Since the T4 DPLL always operates in revertive mode, the
forced clock automatically becomes the selected reference (as specified in PTAB1:SELREF) as well.
When a reference is forced, the activity monitor for that input continues to operate and affect the relevant ISR,
VALSR
switch to another input clock. See Section 7.6.3.
