Memory access, when turned on, sets the
MEMORY
bit in the
Processing
Element
Features
CAR and indicates that the processing element has physically addressable
local address space that can be accessed as an endpoint through non-maintenance
operations. This local address space may be limited to local configuration registers, or
can be on-chip SRAM, or another memory device.
