Section 14 IEBus™ Controller (IEB) [H8S/2258 Group]
14.3.21 IEBus Receive Status Register (IERSR)
IERSR detects receive data ready, receive start, transmit/receive normal completion, or receive
completion with an error. Each status flag in IERSR corresponds to a bit in the IEIER that
enables/disables each interrupt.

Description
Receive Data Ready
Indicates that the receive data is stored in IERBR and that
the receive data can be read. This flag is automatically
cleared by DTC * data transfer. When data is transmitted by
the CPU, this flag must be cleared by software.
[Setting condition]
When data reception has been completed normally and
receive data has been loaded to IERBR.
[Clearing conditions]

Reserved
These bits are always read as 0 and cannot be modified.
Receive Start Detection
Indicates that the IEB starts reception.
