2.9.4
The external address space is accessed with an 8-bit or 16-bit data bus width in a two-state or three-state bus cycle. In
three-state access, wait states can be inserted. For further details, refer to section 6, Bus Controller.
2.10
2.10.1
Only register ER0, ER1, ER4, or ER5 should be used when using the TAS instruction. The TAS instruction is not
generated by the Renesas H8S and H8/300 Series C/C++ compilers. If the TAS instruction is used as a user-defined
intrinsic function, ensure that only register ER0, ER1, ER4, or ER5 is used.
