Display data input to the command / data register (C / D = LOW) is divided into the first four bits and the last four
bits, with the specified DDRAM address being written to the first four, and the specified address + 1 being written to
the last four. The four bits of display data are written sequentially to the bits of the DDRAM, starting from the MSB on
both sides.

When a DDRAM Write command is input (C / D = HIGH), the four bits of display data in the DDRAM Write command
are written to the specified DDRAM address. The four bits are written sequentially, starting from the MSB, to the bits
of the DDRAM, starting with the MSB of the DDRAM.

(4) Timing generator
Connecting Rf between OSC1 and OSC2 causes oscillation of the internal oscillator circuit and generates a display
timing signal. Operation can also be initiated by inputting an external clock.
