HD66724/HD66725
The following operations correspond to the numbers listed in figure 2:
1. Determine the correspondence between character codes and character patterns.
2. Create a listing indicating the correspondence between EPROM addresses and data.
3. Program the character patterns into an EPROM.
4. Send the EPROM to Hitachi.
5. Computer processing of the EPROM is performed at Hitachi to create a character pattern listing, which
is sent to the user.
6. If there are no problems within the character pattern listing, a trial LSI is created at Hitachi and samples
are sent to the user for evaluation. When the user confirms that the character patterns are correctly
written, Hitachi will commence LSI mass production.
