Section 14 IEBus™ Controller (IEB) [H8S/2258 Group]
(4) When an Error Occurs in Broadcast Reception (DEE = 1)
Figure 14.10 shows an example in which a receive error occurs because the receive preparation
cannot be completed (the RxRDY flag is not cleared) until the control field is received in
broadcast reception after the slave reception while the DEE bit is set to 1.
Note: The same as the case in which the RE bit is not set before the control field reception.
