mine the input clock selection, as shown in
Table 6: Input Clock Selection for T0 Path
pendently from T0 path, as determined by the T4_LOCK_T0 bit. When
the T4 DPLL locks to the T0 DPLL output, the T4 selected input clock is
a 77.76 MHz or 8 kHz signal from the T0 DPLL 77.76 MHz path (refer to
Chapter 3.11.5.1 T0
the T4 path locks independently from the T0 path, the T4 DPLL input
clock selection is determined by the T4_INPUT_SEL[3:0] bits. Refer to
