Total: 65 types

Legend: B: Byte

W: Word

L: Longword

Notes: 1. POP.W Rn and PUSH.W Rn are identical to MOV.W @SP+, Rn and MOV.W Rn,

@-SP. POP.L ERn and PUSH.L ERn are identical to MOV.L @SP+, ERn and MOV.L

ERn, @-SP.

2. Bcc is the general name for conditional branch instructions.

3. Cannot be used in the H8S/2138 Group or H8S/2134 Group.

4. Only register ER0, ER1, ER4, or ER5 should be used when using the TAS instruction.

5. Only registers ER0 to ER6 should be used when using the STM/LDM instruction.
