(3) Securement of communication serial interface
The INTP pin is used for communication between MINICUBE2 and the target system. The settings related to
the INTP pin are performed by the debug monitor program, but if the setting is changed by the user program, a
communication error may occur.
To prevent such a problem from occurring, communication serial interface must be secured in the user
program.
[How to secure communication serial interface]
Create the user program observing the following points.
• Interrupt mask flag register
• Port mode registers of alternate-function ports
• External interrupt mode registers
Example
Example
Example
Do not disable interrupts using the interrupt mask flag register corresponding to the INTP pin used.
Do not set to other than the rising edge the external interrupt mode register corresponding to the INTP
pin used.
Do not set to the output mode the alternate-function port corresponding to the INTP pin used.
Setting other than below is prohibited when the target device is the 78K0S/KB1+ and INTP3 is
used.
Setting other than below is prohibited when the target device is the 78K0S/KB1+ and INTP3 is
used.
Setting other than below is prohibited when the target device is the 78K0S/KB1+ and INTP3 is
used.
