Incorrect memory access for CMOS NOPs $dc and $fc #19
Description
$dc and $fc are NOPs with abs addressing. According to https://laughtonelectronics.com/Arcana/KimKlone/Kimklone_opcode_mapping.html, they should behave exactly as other instructions with abs addressing, just the result is discarded. Json tests assume incorrect last memory read - it repeat last byte of instruction, while it should read the memory at abs address.
