Note that the MSB’s of the DATA (D7) and the EXTENDED DATA (E7) are in the fourth byte.
Terminology:
• TO PC is the “DESTINATION BIT”
• I4..I0 is the “INSTRUCTION”
• D7..D0 is the “DATA”
• E7..E0 is the “EXTENDED DATA”
• A0 is the “LSB of the MACHINE ADDRESS”
The destination bit, TO PC, is 0 when sending from the PC to the machine, or 1 when sending from the machine to the PC.
