■Function Specifications

Table 3.1-1 lists the major function specifications of the adapter. Figure 3.1-1 is a block diagram of external-memory emulation.

	Table 3.1-1 Adapter Function Specifications
Item		Description
	Serving as the adapter used in combination with the DSU-FR emulator and header
Adapter Function	to provide connection between the emulator and evaluation MCU and between the
	evaluation MCU and user system.
External trace memory	Supporting the external trace function. Trace length of 64 K frames
Internal ROM emulation	Supporting the internal ROM emulation memory function. 1 megabytes max. *1
	Supporting the external-memory emulation *2 function. Capable of setting RAM/
	ROM. This function is implemented by mounting an optional memory board on
	the adapter board.
	Memory capacity	Capable of selecting the capacity of the memory board
		from among seven steps between 2M words and 32K
	switching
		words (1 word = 16 bits).
External-memory emulation
		Capable of disconnecting address lines disabled by the
		memory capacity switching function from buffers and us-
		ing them as user resources instead.
	Memory connection	Also capable of reducing the load applied during use of
		such address lines as user resources by disconnecting
		them even when the external-memory emulation function
		is not used.
Power-on debugging	Supporting the power-on debug function *3 which runs a program immediately af-
	ter the power-on sequence of the evaluation MCU.
Jumper plugs	The jumper plugs on the adapter board can be used to make various settings of the
	adapter.
	The IC sockets for oscillator on the adapter board supply clock signals from the
Clock input IC sockets	adapter to the main clock (X0/X1) and subclock (X0A/X1A) pins of the evalua-
	tion MCU.

*1 : The evaluation MCU must support the external-memory emulation feature. The total amount of memory available depends on the memory capacity of the memory board, its memory ca- pacity select switch, and the settings of the evaluation MCU. Refer to the "Evaluation MCU Hardware Manual" or Please ask, when unknown before use. For details, see Section 5.4 "Ex- ternal-Memory Emulation Settings."

Note also that this function is added to the external bus of the evaluation MCU. Before using the function, read Chapter 6 "Cautions" carefully.

*2 : This function assumes that the evaluation MCU supports the power-on debug feature. Refer to the "Evaluation MCU Hardware Manual" or Please ask, when unknown before use.
