(5) Securement of communication serial interface
• On-chip debug mode register (OCDM)
• Serial interface registers
• Interrupt mask register
UARTC0, CSIF0, or CSIF3 is used for communication between MINICUBE2 and the target system. The
settings related to the serial interface modes 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]
Do not set the registers related to CSIF0, CSIF3, or UARTC0 in the user program.
When CSIF0 is used, do not mask the transfer end interrupt (INTCF0R). When CSIF3 is used, do not mask
the transfer end interrupt (INTCF3R).
interrupt (INTUC0R).
For the on-chip debug function using the UARTC0, CSIF0, or CSIF3, set the OCDM register functions to
normal mode. Be sure to set as follows.
• Input low level to the P56/INTP05/DRST pin.
• Set the OCDM0 bit as shown below.
(a) When CSIF0 is used
(b) When CSIF3 is used
(C) When UARTC0 is used
Remark ×: don’t care
<1> Clear the OCDM0 bit to 0.
<2> Fix the P56/INTP05/DRST pin input to low level until the processing of <1> is complete.
