/* Form 1 instructions come in different flavors:
21
 
22
    Some have no arguments                          (MOXIE_F1_NARG)
23
    Some only use the A operand                     (MOXIE_F1_A)
24
    Some use A and B registers                      (MOXIE_F1_AB)
25
    Some use A and consume a 4 byte immediate value (MOXIE_F1_A4)
26
    Some use just a 4 byte immediate value          (MOXIE_F1_4)
27
    Some use just a 4 byte memory address           (MOXIE_F1_M)
28
    Some use B and an indirect A                    (MOXIE_F1_AiB)
29
    Some use A and an indirect B                    (MOXIE_F1_ABi)
30
    Some consume a 4 byte immediate value and use X (MOXIE_F1_4A)
31
    Some use B and an indirect A plus 4 bytes       (MOXIE_F1_AiB4)
32
    Some use A and an indirect B plus 4 bytes       (MOXIE_F1_ABi4)
33
 
34
  Form 2 instructions also come in different flavors:
35
 
36
    Some have no arguments                          (MOXIE_F2_NARG)
37
    Some use the A register and an 8-bit value      (MOXIE_F2_A8V)
38
 
39
  Form 3 instructions also come in different flavors:
40
 
41
    Some have no arguments                          (MOXIE_F3_NARG)
42
    Some have a 10-bit PC relative operand          (MOXIE_F3_PCREL).  */
