#161113 - and bank switching ? Responding to: ???'s previous message |
Andy Neil said:
Also, accessing these locations via their "Rn" names is quicker than accessing them via their absolute addresses - but is limited to just these 32 locations. This is exactly what is intrigating me. If we access them directly with Rxx, it's quicker than access to ram location directly only if we are in the good bank. If we need bank switching, it will be slower (one more operation). Are there any instructions that does work only with the Rxx notation and not with direct addressing ? Regards |
