/* Form 1 instructions come in different flavors:
Some have no arguments (MOXIE_F1_NARG)
Some only use the A operand (MOXIE_F1_A)
Some use A and B registers (MOXIE_F1_AB)
Some use A and consume a 4 byte immediate value (MOXIE_F1_A4)
Some use just a 4 byte immediate value (MOXIE_F1_4)
Some use just a 4 byte memory address (MOXIE_F1_M)
Some use B and an indirect A (MOXIE_F1_AiB)
Some use A and an indirect B (MOXIE_F1_ABi)
Some consume a 4 byte immediate value and use X (MOXIE_F1_4A)
Some use B and an indirect A plus 4 bytes (MOXIE_F1_AiB4)
Some use A and an indirect B plus 4 bytes (MOXIE_F1_ABi4)
Form 2 instructions also come in different flavors:
Some have no arguments (MOXIE_F2_NARG)
Some use the A register and an 8-bit value (MOXIE_F2_A8V)
Form 3 instructions also come in different flavors:
Some have no arguments (MOXIE_F3_NARG)
Some have a 10-bit PC relative operand (MOXIE_F3_PCREL). */
