Section 17 IEBus™ Controller (IEB) [H8S/2552 Group]
17.3.9
IETBR is a 1-byte buffer to which data to be transmitted in master or slave transmission is written.
IETBR is empty when the TxRDY flag in IETSR is 1. Check the TxRDY flag before setting
transmit data in IETBR.
Data written in IETBR is transmitted in the data field in master or slave transmission. Figure 17.6
shows the correspondence between the communications signal format and registers for IEBus data
transfer.
