Section 14 IEBus™ Controller (IEB) [H8S/2258 Group]
14.3.4
IEAR1 sets the lower 4 bits of the master unit address and communications mode. In master
communications, the master unit address becomes the master address field value. In slave
communications, the master unit address is compared with the received slave address field.

Reserved
This bit is always read as 0 and cannot be modified.
Slave Transmission Setting
Sets bit 4 in the slave status register. Transmitting the
slave status register informs the master unit that the slave
transmission enabled state is entered by setting this bit to
1. Note that this bit only sets the slave status register value
and does not affect slave transmission directly.
0: Bit 4 in the slave status register is 0 (slave transmission
1: Bit 4 in the slave status register is 1 (slave transmission
stop state)
enabled state)
