5.3.4. Summary of Specification Restrictions
Summary of specification restrictions is shown.
1) Communication mode (*1): Normal UART
Note:
When doing debugging from shutdown standby mode, be sure to keep the device unconnected to the OCD
tool.
When starting to debug the device connected to the OCD tool, the tool can be enabled by the MDI wakeup
function. If, however, the device is being in stop mode (power-shutdown) or in watch mode
(power-shutdown), it is impossible to start debugging. This is because, in both the modes, power supply to the
OCDU is cut off and consequently the OCDU cannot receive a signal to enable its operation. Start debugging
in other mode than the standby mode (power-shutdown).
