System Configuration and Protection
6.1.1.1
Some of the functions defined in the various sections of the USIU (external bus interface, memory
controller, and general-purpose I/O) share pins.
multiplexed pins are assigned.
6.1.1.2
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 determines the priority of an external master’s arbitration
request. The operation of the internal arbiter is described in
6.1.2
External master modes are special modes of operation that allow an alternative master on the external bus
to access the internal modules for debugging and backup purposes. They provide access to the internal
buses (U-bus and L-bus) and to the intermodule bus (IMB3).
There are two external master modes:

Peripheral mode (enabled by setting PRPM in the external master control (EMCR) register) uses a
special slave mechanism that shuts down the RCPU and an alternative master on the external bus
can perform accesses to any internal bus slave.
