Plane Priority Order: The display priority order for planes is set using DPPR; if one plane is set
in two or more places in the priority order, the place with highest priority is selected.
For example, if the setting in DPPR is H'00CBD888, then the results of the priority order and
display on/off settings are as follows.
19.4.11 Blinking
For each plane, blinking operation can be performed by using the display area start address 0 and
1 registers.
Usually, double buffer control is performed for each plane according to the setting of the PnBM
bit in PnMR. However, blinking is performed with the period specified by the PnBTA and PnBTB
bits in PnBTR by setting the PnBM bits in PnMR to 10 (Auto display change mode (blinking
mode)). If the PnBTA and PnBTB bits are set to 0, operation is the same as when set to 1.
