CSSL27: A/D Input Band Gap Scan Selection bit
1 = Band gap divided-by-six reference (VBG/6) is selected for input scan
0 = Analog channel is omitted from input scan
CSSL26: A/D Input Band Gap Scan Selection bit
1 = Internal core voltage (VCAP) is selected for input scan
0 = Analog channel is omitted from input scan
CSSL25: A/D Input Half Band Gap Scan Selection bit
1 = Band gap reference (VBG) is selected for input scan
0 = Analog channel is omitted from input scan
CSSL24: A/D Input Band Gap Scan Selection bit
1 = Band gap divided-by-two reference (VBG/2) is selected for input scan
0 = Analog channel is omitted from input scan
CSSL<23:16>: Analog Input Pin Scan Selection bits⁽¹⁾
1 = Corresponding analog channel selected for input scan
0 = Analog channel is omitted from input scan
Note 1: Unimplemented in 64-pin devices, read as ‘0’.
