The following code example shows how to program the
pullup control registers.
First the MODE register is loaded with 1Eh to select write
access to the pullup control registers (PLP_A, PLP_B,
and so on). Then the MOV !rx,W instructions are used to
specify which port pins are to be connected to the inter-
nal pullup resistors. Setting a bit to 1 disconnects the cor-
responding pullup resistor, and clearing a bit to 0
connects the corresponding pullup resistor.
