nBW
OS8
Not byte/word. This is an output signal used by the processor to indicate to the external
memory system when a data transfer of a byte length is required. The signal is HIGH for
word transfers and LOW for byte transfers and is valid for both read and write cycles. The
signal will become valid during phase 2 of the cycle before the one in which the transfer will
take place. It will remain stable throughout phase 1 of the transfer cycle.
nCPI
O4
Not Coprocessor instruction. When ARM60 executes a coprocessor instruction, it will take
this output LOW and wait for a response from the coprocessor. The action taken will depend
on this response, which the coprocessor signals on the
CPA
and
CPB
inputs.
nFIQ
I
Not fast interrupt request. This is an asynchronous interrupt request to the processor which
causes it to be interrupted if taken LOW when the appropriate enable in the processor is
active. The signal is level sensitive and must be held LOW until a suitable response is
received from the processor.

Not interrupt request. As

nMREQ
O4
Not memory request. This signal, when LOW, indicates that the processor requires memory
access during the following cycle. The signal becomes valid during phase 1, remaining valid
through phase 2 of the cycle preceding that to which it refers.
nOPC
O4
Not op-code fetch. When LOW this signal indicates that the processor is fetching an
instruction from memory; when HIGH, data (if present) is being transferred. The signal
becomes valid during phase 2 of the previous cycle, remaining valid through phase 1 of the
referenced cycle.
