PMP configurations for load and store addresses may have different permissions (e.g., "R" vs. "RW"). Due to the timing alignment of internal signals, the address permission check may be incorrectly applied during the second part of a misaligned access transaction. As a workaround, insert two instructions (e.g. ADDI/NOP) between accessing to different memory regions. This spacing avoids the false permission check caused by signal timing overlap.
