are extracted and added to the page number that holds the lookup table. The corresponding
lookup table content is mapped to the 64-byte paging window, $00C0 to $00FF. Then the six
least significant bits (LSB) of the variable SensorReading is used as an index to read out the
upper memory content directly from the paging window.
