PUmn Pmn pin on-chip pull-up resistor selection
0 On-chip pull-up resistor not connected
1 On-chip pull-up resistor connected
Note 1. This bit can be only manipulated when the P125/INTP1/(VCOUT0)/(VCOUT1)/(SI01) pin is selected
(PORTSELB = 0) (the on-chip pull-up resistor is always valid (PU125 = 1) when the RESET
