8.4 Macro Service
This function is to transfer data between memory and a special function register (SFR) without intervention by the
CPU. A macro service controller accesses the memory and SFR in the same transfer cycle and directly transfers
data without loading it.
Because this function does not save or restore the status of the CPU, or load data, data can be transferred at high
speeds.
