In order to avoid floating nodes the ports should be either configured as outputs by setting the
data direction register (DDRH at Base+$0262) to $FF, or enabling the pull resistors by writing
a $FF to the pull enable register (PERH at Base+$0264).
Port J pull-up resistors are enabled out of reset on all four pins (7:6 and 1:0). Therefore care must
be taken not to disable the pull enables on PJ[1:0] by clearing the bits PERJ1 and PERJ0 at
Base+$026C.
Port K pull-up resistors are enabled out of reset, i.e. Bit 7 = PUKE = 1 in the register PUCR at
Base+$000C. Therefore care must be taken not to clear this bit.
