32-bit address bus used to address any of 4 Gbytes
32-bit data bus used to transfer up to 32 bits of data per bus transfer
Indicates the general transfer type : normal, MOVE 16, alternate logical
function code, and acknowledge
Indicates supplemental information about the access
Indicates which cache line in a set is being pushed or loaded by the
current line transfer
User-defined signals, controlled by the corresponding user attribute bits
from the address translation entry
Identifies the transfer as a read or write
Indicates the data transfer size. These signals, together with A0 and
A1, define the active sections of the data bus
Indicates a bus transfer is part of a read-modify-write operation, and
that the sequence of transfers should not be interrupted
Indicates the current transfer is the last in a locked sequence of transfer
Indicates the processor will not cache the current bus transfer
Indicates the beginning of a bus transfer
Asserted for the duration of a bus transfer
Asserted to acknowledge a bus transfer
Indicates an error condition exists for a bus transfer
Indicates the current bus transfer should not be cached
Indicates the slave cannot handle a line burst acces
Alternate clock input used to latch input data when the processor is
operating in DLE mode
Indicates the snooping operation required during an alternate master
access
Inhibits memory devices from responding to an alternate master access
during snooping operations
Asserted by the processor to request bus mastership
Asserted by an arbiter to grant bus mastership to the processor
Asserted by the current bus master to indicate it has assumed
ownership of the bus
Dynamically disables the internal caches to assist emulator support
Disables the translation mechanism of the MMUs
Processor reset
Asserted during execution of the RESET instruction to reset external
devices
Provides an encoded interrupt level to the processor
Indicates an interrupt is pending
Used during an interrupt acknowledge transfer to request internal
generation of the vector number
Indicates internal processor status
Clock input used to derive all bus signal timing
