The Sensor Controller can access the AUX domain module registers through the I/O address space. I/O addressing is 8-bit oriented (an address increment of 1 corresponds to 1 byte), except for the register aliasing space, that is addresses 0 to 255, where each entry maps to a 16-bit register.
I/O registers are accessed through input and output instructions, supporting:
Unaligned 16-bit accesses are not supported.
There is no access to registers outside of the AUX domain. Also, there is no access to the AUX RAM and AUX_SCE module through the I/O address space.
