OVERVIEW
The SED1210F is a Liquid Crystal Display (LCD)
character display controller/driver, capable of directly
driving displays of up to 16 characters. If an external
expansion driver is used, displays of up to 40 characters
can be generated.
The SED1210F has an internal character generator (CG)
consisting of 160 JIS ASCII characters in ROM and four
user definable characters in RAM. The internal CG,
combined with a versatile set of cursor and display
control commands, means that the system CPU is only
responsible for the display data and commands, and not
for the LCD display itself.
