CHAPTER  19    IEBus  CONTROLLER  (V850/SB2)

User’s Manual  U13850EJ4V0UM

443

If the control bit received from the master unit is not as shown in Table 19-3, the unit locked by the master
unit rejects acknowledging the control bit, and does not output the acknowledge bit.

Moreover, units for which lock is not set by the master unit reject acknowledgement and do not output an
acknowledge bit when the control data shown in Table 19-4 is acknowledged.
