powered with sufficient voltage (see specification below). Below the specified supply voltage, only voltages that are
close to VSS or VBAT can be switched.
When PBAna[x] is set to 1, one pad of the Port B terminals is changed from digital I/O mode to analog. The usage
of the registers RegPBPullup, RegPBOut and RegPBDir define the analog configuration (see Table 12-9).
When PBAna[x] = 1, then PBPullup[x] connects the pin to the analog bus. PBDir[x] and PBPOut[x] select which
of the 4 analog lines is used.

Table 12-9: Selection of the analog lines with RegPBDir, RegPBout and RegPBPullup when PBAna[x] = 1
Set the pads PB[2] and PB[5] on the analog line 3. (the values X depend on the configuration of others
pads)
apply high impedance in the analog mode (move RegPBPullup,#0bXX0XX0XX)
go to analog mode (move RegPBAna,#0bXX1XX1XX)
select the analog line3 (move RegPBDir,#0bXX1XX1XX and move RegPBOut,#0bXX1XX1XX)
apply the analog line to the output (move RegPBPullup,#0bXX1XX1XX)
