H'3FF: 1024 fields are stored.
Note: After data has been written for the specified number of fields, the memory is overwritten by
new video data from the first address.
Video data is stored at a 1/2-field rate (NTSC: 30 fps; PAL: 25 fps).
When the VIDEO_MAIN_EXE bit in the VIDEO_MODE register is cleared to 0, the address
calculation result is initialized and data is written to the initial field storing area.
