The EM65570S execute address conversion that depends on control register setting.
In case of auto increment mode, usually AX register is added one. For instance when
REF and AXI are both “1”, AX register is added one, but effective X address seems
decrement because of address conversion. The effective Y address uses AY register
values as it is.
