This LSI has an on-chip one-channel IEBus controller (IEB). The Inter Equipment Bus™
(IEBus™)*
This LSI does not have an on-chip IEBus driver/receiver, so it is necessary to mount a dedicated
driver/receiver*

17.1
• IEBus protocol control (layer 2) supported
• Data transfer by the data transfer controller (DTC)
• Operating frequency
Note: When selected communications mode 0 or mode 1 (± 1.5 %)
• Noise resistance is improved by mounting the IEBus driver/receiver (layer 1) externally.
• Module stop mode can be set.
