3.3.12 Evaluation environment
(1) Overview
The development environment which can be used on this board is as follows.
CPU Built-in FLASH writing
- FL-PR4, FL-PR5
Debugging
-
MINICUBE,
MINICUBE2
It is designing on the assumption that the four above-mentioned kinds.
This board mounts the connector for FL-PR4, FL-PR5 connection in built-in FLASH writing.
The connector for FL-PR4, FL-PR5 connection is as common as the connector for MINICUBE2.(CN5)
Moreover, the connector for MINICUBE connection is mounted.(CN6)
A block diagram is shown in the following clause.
In circuit composition, FL-PR4, FL-PR5, MINICUBE2(CN5) and MINICUBE(CN6) constitute exclusion use
as a premise.
If FL-PR4, FL-PR5, or MINICUBE2(CN5) and MINICUBE(CN6) are connected simultaneously, since it may
be failure, please avoid concurrent use by a signal collision occurring.
(2) Setup
A setup of the following jumper (JP7) is changed according to the development environment to be used.
JP7 Function
1-2 short circuit
Normal use, During connecting FL-PR4, FL-PR5, MINICUBE (Default)
2-3 short circuit
During connecting MINICUBE2
Table 3.3.12 (2)
In case FL-PR4, FL-PR5 and MINICUBE are used, a JP7 short pin is set to the "1-2" side, and it is set as
the course of dashed-and-dotted line (FL-PR4, FL-PR5) and a dotted line (MINICUBE).
(Refer to Figure 4.3.7)
In case MINICUBE2 is used, a JP7 short pin is set to the "2-3" side, and it is set as the course of solid line
(MINICUBE2).
Please use a JP7 short pin for the "1-2" side at the time of real operation, setting it up (when you do not use
a debugger).
