Old systems have a total of 7 masters (guesses are ARM11, ARM9, GPU, DSP, CDMA, CSND, AHB); new systems have 3 additional masters (likely NewCDMA and L2 controller, and N3DS-GPU (enabled by [[CONFIG11_Registers#CFG11_GPU_N3DS_CNT\|CFG11_GPU_N3DS_CNT]])).

	GSP limits the maximum value of tidemark to 7; meanwhile, the maximum value for access control is 2^N-1, 1 bit for each slave interface, where N = number of slave interfaces.		GSP limits the maximum value of tidemark to 7; meanwhile, the maximum value for access control is 2^N-1, 1 bit for each slave interface, where N = number of slave interfaces.

	New GSP forces SI7 to be always set.		New GSP forces SI7 (corresponding to N3DS-GPU) to be always set.
