Section 17 IEBus™ Controller (IEB) [H8S/2552 Group]
17.3.14 IEBus Receive Buffer Register (IERBR)
IERBR is a 1-byte read-only buffer that stores data received in master or slave reception. This
register can be read when the RxRDY flag in IERSR is set to 1. This register indicates the data
field value both in master and slave receptions. This register cannot be modified.
Figure 17.7 shows the relationship between transmission signal format and registers in IEBus data
reception.
