Section 14 IEBus™ Controller (IEB) [H8S/2258 Group]
14.3.7
IESA2 sets the upper 8 bits of the communications destination slave unit address. For slave
communications, it is not necessary to set this register.
14.3.8
IETBFL sets the message length for master or slave transmission.

Description
Upper 8 Bits of IEBus Slave Address
Set upper 8 bits of the communications destination
slave unit address
Description
Transmit Message Length
Set the message length for master or slave
transmission.
If a value exceeding the maximum transmit bytes
for one frame is set in IETBFL, communications
are performed with two or more frames in some
communications modes. In this case, in or after the
second frame, the message length value should be
the number of bytes of the remaining
communications data, however, the initial IETBFL
setting remains unchanged. Therefore, for the
second frame or after, re-set the number of bytes
of the remaining communications data.
