Selecting The Processor Mode; Setting The Emulation Memory; Emulation Memory Allocation As Expansion Area - Renesas Emulation Pod for M16C/80 Group MCUs M30803T-RPD-E User Manual

(2) Selecting the Processor Mode

Here explains about the setting of processor mode. Selectable modes are listed in Table 4.1.
Table 4.1 Selecting the processor mode
Processor mode
Single-chip mode
Memory expansion mode
Microprocessor mode
Notes on Selecting the Processor Mode:
• When setting single-chip mode and memory expansion mode, the level of the
CNVss pin of the target system should be "L".
• When setting microprocessor mode, the level of the CNVss pin of the target system
should be "H".
• When setting memory expansion mode or microprocessor mode, the RDY* and
HOLD* pins of the target system should be "H".

(3) Setting the Emulation Memory

This product has two emulation memory and how to allocate is different depending on which
processor mode is selected. Table 4.2 shows how to set the emulation memory for each processor
mode.

(4) Emulation Memory Allocation as Expansion Area

This section explains about setting emulation memory for expansion purposes in the memory
expansion mode and microprocessor mode. To use emulation memory as expansion area, set memory
allocation as indicated here below. Emulation memory specifications are given in Table 4.3.
(1) Setting bank address (Bank):
For example, specifying "C0" allocates the bank from address C00000h.
When 256 KB is specified as the Length, bank addresses can be specified in 256KB blocks up to
00, 04, 08 and - FC.
When 1 MB is specified as the Length, bank addresses can be specified in 1MB blocks up to 00,
10, 20 and - F0.
