Bits 7 and 6: Digital2 Frequency (DIG2F[1:0]). This field, MCR6:DIG2SS, and MCR6:DIG2AF configure the
frequency of the Digital2 clock synthesizer.
Bits 5 and 4: Digital1 Frequency (DIG1F[1:0]). This field and MCR6:DIG1SS configure the frequency of the
Digital1 clock synthesizer.
Bit 1: Digital2 Source (DIG2SRC). This bit selects which DPLL the Digital2 DFS is connected to. When
MCR4:LKT4T0 = 1 it is always connected to the T0 DPLL.
Bit 0: Digital1 Source (DIG1SRC). This bit selects which DPLL the Digital1 DFS is connected to. When
MCR4:LKT4T0 = 1 it is always connected to the T0 DPLL.
