I am new on ARM, my last controller was a 16bit Fujitsu. I see that the controller has instructions to pick smaller data from accu, but I could not find anything about penalty cycles when PC or SP get unaligned (or if it is even possible).
Can somebody tell me how this controller behave? I have bad experiences with 16 bit controllers especially when SP got unaligned due to smaller stack data.
I would appreciate any help.
