| /* Form 1 instructions come in different flavors: | |
| Some have no arguments (MOXIE_F1_NARG) | |

| 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 2 byte offset (MOXIE_F1_AiB2) | |
