These bits select an input to OUT7.
0000 ~ 0011: The output of T0 APLL. (default: 0000)
0100: The output of T0 DPLL 77.76 MHz path.
0101: The output of T0 DPLL 12E1/24T1/E3/T3 path.
0110: The output of T0 DPLL 16E1/16T1 path.
0111: The output of T0 DPLL GSM/OBSAI/16E1/16T1 path.
1000 ~ 1011: The output of T4 APLL.
1100: The output of T4 DPLL 77.76 MHz path.
1101: The output of T4 DPLL 12E1/24T1/E3/T3 path.
1110: The output of T4 DPLL 16E1/16T1 path.
1111: The output of T4 DPLL GSM/GPS/16E1/16T1 path.
These bits select a division factor of the divider for OUT7.
The output frequency is determined by the division factor and the signal derived from T0/T4 DPLL or T0/T4 APLL output
(selected by the OUT7_PATH_SEL[3:0] bits (b7~4, 71H)). If the signal is derived from one of the T0/T4 DPLL outputs,
please refer to
Table 25

for the division factor selection.
Table 24
