Chapter 5 External Bus Interface (S12XEBIV4)
state operation (stretching) of the external bus access is done in emulation modes when accessing internal
memory or emulation memory addresses.
In both modes observation of the internal operation is supported through the external bus (internal
visibility).
5.5.2.1
This mode is used for emulation systems in which the target application is operating in normal single-chip
mode.

Signals muxed with address lines ADDRx, i.e., IVDx, IQSTATx and ACCx, have the same timing.
LSTRB has the same timing as RW.
