Two bits in the SIUMCR control USIU bus arbitration. The external arbitration (EARB)
bit determines whether arbitration is performed internally or externally. If EARB is
cleared (internal arbitration), the external arbitration request priority (EARP) bit deter-
mines the priority of an external master’s arbitration request. The operation of the in-
ternal arbiter is described in
