Notes: B: byte size; W: word size; L: longword size.
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/2169 or H8S/2149.
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.
