Table A-2 Instruction memory interface signals
Description
The processor instruction address bus.
This is an input that allows the memory system to
tell the processor that the requested instruction
memory access is not allowed.
This bus is used to transfer instructions between the
memory system and the processor.
This is an input that allows external hardware to
halt the execution of the processor for debug
purposes. If HIGH at the end of an instruction
Fetch it causes the ARM9E-S to enter debug state if
that instruction reaches the Execute stage of the
processor pipeline.
If LOW at the end the cycle, then the processor
requires a memory access during the following
cycle.
These contain the current mode of the processor
and are valid with the address.
When LOW the processor is in User mode, when
HIGH the processor is in a privileged mode. This
signal is valid with the address.
If HIGH at the end of the cycle then any instruction
memory access during the following cycle is
sequential from the last instruction memory access.
When HIGH the processor is in Thumb state, when
LOW the processor is in ARM state. This signal is
valid with the address.
