After the increment control register has been set. be sure to assign address to the X and Y address registers starting from the
lowest bit. Because it is not assuring the data of X and Y address register after setting increment control register. The
increment control of X and Y address by AIM, AYI, AXI registers is as follows.
(1) Regardless of AIM, no increment for AX and AY register.
(2) According to the setting-up of AIM, automatically change X address.
In accordance with the REF register, AX register and X address becomes as follows.
Note: maxH: The internal maximum X-address in each access mode.
(3) According to the setting-up of AIM, automatically change Y address. Regardless of REF, increment by loop of
(4) According to the setting-up of AIM, cooperative change X and Y address. When the X address exceed maxH, Y
Note: maxH: The internal maximum X-address in each access mode.
