(4) Securement of communication serial interface
• Serial interface registers
• Interrupt mask register
• Port registers when UARTA0 is used
UARTA0 or CSIB0 is used for communication between MINICUBE2 and the V850E/IF3, V850E/IG3. 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 UARTA0 and CSIB0 in the user program.
When UARTA0 is used, do not mask the reception end interrupt (INTUA0R). When CSIB0 is used, do not
mask the reception end interrupt (INTCB0R).
When UARTA0 is used for communication, port registers are set to make the TXDA0 and RXDA0 pins valid
by the debug monitor program. Do not change the following register settings with the user program during
debugging. (The same value can be overwritten.)
(a) When UARTA0 is used
(b) When CSIB0 is used
