Field Encoding
The convention for opcode binary format is shown in the following Tables. For example,
to get the opcode format on the instruction LD (IX+12h), C; first find out the entry for LD
(XY+d),r. That entry has an opcode format of:
At the bottom of each Table (between Table and Notes), the binary format is the following:
r,r’ Reg
000 B
001 C
010 D
011 E
100 H
101 L
111 A
To form the opcode first look for the y field value for the IX register, which is 0. Then find
r field value for the C register, which is 001. Replace the y and r fields with the value from
the table; replace d value with the real number. The results are:
76 543 210
