Section 14 IEBus™ Controller (IEB) [H8S/2258 Group]
14.3.22 IEBus Receive Interrupt Enable Register (IEIER)
IEIER enables/disables IERSR reception ready, receive start, transmit/receive normal completion,
and receive completion with an error interrupts.
14.3.23 IEBus Receive Error Flag Register (IEREF)
IEREF checks the source of an RxE interrupt indicated in IERSR. This register detects an overrun
error, timing error, overflow of a maximum number of bytes in one frame, and parity error.
These flags become valid when the receive start flag (RxS) is set to 1. If an error occurs before the
RxS flag is set to 1, the IEB terminates the communications and enters the wait state. In this case,
these flags will not be set and the RxE flag is not set.
