----------------------------------------------------------- DIP switch positions to control the 5 least significant bits: pos #1 = bit 4 // pos #2 = bit 3 // pos #3 = bit 2 // pos #4 = bit 1 // pos #5 = bit 0
-------------------------------------------------------------- Example: bottom switch at pos #1 to the left (=ON), all other to the right --> 0b(fix:010)1'0000 = 0x50 = 'P'
-------------------------------------------------------------- Example: bottom switch at pos #2 and #3 to the left (=ON), all other to the right --> 0b(fix:010)0'1100 = 0x4C = 'L'
