Display RAM Reading by LCD Controller:
Data is read by the HD66410 to be displayed asynchronously
with accesses by the MPU. However, because simultaneous access could damaging data in the display
RAM, the HD66410 internally arbitrates access timing; access by the MPU usually has priority and so
access by the HD66410 is placed between accesses by the MPU. Accordingly, an appropriate time must be
secured (see the given electrical characteristics between two accesses by the MPU).
