CPU address space
Preliminary User’s Manual U17566EE1V2UM00
The entire CPU address space can be used for operand addresses.
Only the lower 64 MB of the CPU address space can be used for instruction
addresses. When an instruction address for a branch instruction is
calculated and moved to the program counter (PC), then bits 31 to 26 are
set to zero.
