Function
100000: V
100001: V
…
111111 : V
1: selects DLL output as the ADC sampling clock.
0: selects external clock as the ADC sampling clock.
1: selects DLL output as the DAC sampling clock.
0: selects external clock as the DAC sampling clock.
1: enables the input reference clock to the DLL.
Sets DLL divide ratio (1 to 8) at the output of the DLL.
0000: not valid.
0001: 1.
0010: 2.
…
0110: 6.
0111: not valid.
1000: 8.
1001: not valid.
…
1111: not valid.
1: DLL has locked to reference clock (read only).
00: DLL output is directly driven out. Divider is bypassed.
01: DLL output is directly driven out. Divider is bypassed.
10: DLL output is divided by 2.
11: DLL output is divided by 4.
Sets DLL multiplication factor (1 to 32).
00000: 1.
00001: 2.
…
11111: 32.
Set these bits to 0.
Reset DLL. The DLL must be reset by a low to high transition on this bit
each time the DLL configuration is changed or the reference frequency is
changed.
Set these bits to 0.
Sets the number of AUXADCCLK cycles required to perform a conversion.
00: 20 AUXADCCLK cycles.
01: 22 AUXADCCLK cycles.
10: 26 AUXADCCLK cycles.
11: 34 AUXADCCLK cycles.
Selects analog input channel to the auxiliary ADC.
000: AUXIN1, Pin 72.
001: AUXIO2, Pin 71.
010: AUXIO3, Pin 70.
011: internal VPTAT voltage.
100: internal VCMLI voltage.
101: internal VCMLQ voltage.
