The increment control of X and Y-addresses by AIM, AYI and AXI registers are as follows.
(1) Regardless of AIM, no increment for AX and AY register.
(2) Basing on the set-up of the AIM, automatically change the X-address.
In accordance with the REF register, the AX register and X-address becomes as follows.
Note: maxH: internal maximum X-address in each access mode.
(3) Basing on the set-up of the AIM, automatically change the Y-address. Regardless of
(4) According to the set-up of the AIM, simultaneously change the X and Y-address.
Note: maxH: The internal maximum X-address in each access mode.
Following shows address increment in window function access.
