16. IEBusTM Controller
The IEBusTM (Inter-Equipment Bus) is a small-scale, two-wire serial bus interface designed for data transfer
between pieces of equipment.
This interface is applicable, for example, as a bus interface for controlling vehicle-mounted devices.
IEBusTM has the following features:
Multitasking
Any of the units connected to the IEBusTM can transmit data to another one.
Broadcast function (Communication from one unit to multiple units)
Group broadcast : Broadcast to a group of units
All-unit broadcast
: Broadcast to all units
Three modes can be selected for different transmission speeds.
Data buffer for transmission
8-byte FIFO buffer
Data buffer for reception
8-byte FIFO buffer
CPU internal operating frequency (12 MHz, 12.58 MHz)
