Super/subscript generator converts the normal CG pattern (image data) received from an external
device into super/subscript character data.
Italic character generator converts the normal
CG
pattern (image data) received from an external
device into italic character data.
24-bit shift register.
8-bit parallel interface. Automatically latches the data upon receiving the strobe signal, and sets the
BUSY signal HIGH. inputs and outputs other control signals.
When a serial interface is used, multiplexes the two receive data lines (RXD and the seventh bit of
the 8-bit parallel interface) using internal logic, and outputs the result to an external device.
Logically ANDs the two external reset signal inputs using internal logic, and output the result to an
external device (one-channel).
