Bit 7 ( OP2E ) Enable the gain amplifier which input is connected to P64 and output is connected to
the 8-1 analog switch.
0 = OP2 is off ( default value ), and bypasses the input signal to the ADC;
1 = OP2 is on.
Bit 6 ( OP1E ) Enable the gain amplifier whose input is connected to P60 and output is connected to
the 8-1 analog switch.
0 = OP1 is off (default value), and bypasses the input signal to the ADC;
1 = OP1 is on.
Bit 5:Bit 3 (G22 and G20): Select the gain of OP2.
000 = IS x 1 (default value);
001 = IS x 2;
010 = IS x 4;
011 = IS x 8;
100 = IS x 16;
101 = IS x 32;
Legend: IS = the input signal
Bit 2:Bit 0 (G12 and G10 ): Select the gain of OP1.
000 = IS x 1 (default value);
