This bit should be zero.
Select output value of YMON.
0 = YMON output is 0 (YM = Hi-Z).
1 = YMON output is 1 (YM = GND).
Select output value of nYPON.
0 = nYPON output is 0 (YP = External voltage).
1 = nYPON output is 1 (YP is connected with AIN[5]).
Select output value of XMON.
0 = XMON output is 0 (XM = Hi-Z).
1 = XMON output is 1 (XM = GND).
Select output value of nXPON.
0 = nXPON output is 0 (XP = External voltage).
1 = nXPON output is 1 (XP is connected with AIN[7]).
