Operation Differs From That Of Actual Mcus; Cannot Reset From The Target System; Data Values Of Ram Area At Power-On Are Different; Hold* Control - Renesas Emulation Pod M306H2T-RPD-E User Manual

6.3 Operation Differs from That of Actual MCUs

(1) Cannot Reset from the Target System

Set the time for starting up (0.2 Vcc to 0.8 Vcc) to 1 µs or less.

(2) Data Values of RAM Area at Power-on are Different

For this product, 04h is written into the RAM area at power-on. Therefore, the data values are different
from those of an actual MCU.

(3) HOLD* Control

When inputting "Low" to the HOLD* pin to run into the HOLD state, P0
state delaying by 2.5 cycles than the actual MCU (see Figure 5.5 and Table 5.5).

(4) A-D Conversion Values are Different from Expected Values

As a flexible cable, a pitch converter board and other devices are used between the evaluation MCU
and the target system, some characteristics are slightly different from those of the actual MCU.
Therefore, be sure to evaluate your system with an evaluation MCU. Before starting mask production,
evaluate your system and make final confirmation with an CS (Commercial Sample) version MCU.

(5) Outputs of ALE, Address and Others are Different from Those of Actual MCUs

This product has some output signals which are different from those of actual MCU as following.
For details, see Chapter 1 "Note on Differences between Actual MCU and Emulator" (page 17).
1) ALE signal output in accessing the SFR area
2) Address, BHE* and ALE signal outputs in accessing the internal RAM
3) State of the data bus in the stop mode and wait mode
