These pins are used as shown in Figure
4 in master mode, and as shown in
Figure 5 in slave mode.
The following initiation will be proceeded
by setting to initiation.
1) Stops the internal oscillator or the
external oscillator clock input.
2) Initializes the counters of the liquid
crystal display timing generator and
alternating signal (M) generator.
3) Set display off control output (
DOC
)
to low and turns off display.
After reset, display off control output
(
DOC
) will stay low for four more frame
cycles (four clocks of FLM signals) to
prevent error display at initiation. The
electrical characteristics are shown in
Table 4. See Figure 2.
However, when reset is performed
during operation, RAM data in the
HD66520 which is used together with
the HD66503 may be destroyed.
Therefore, write data to the RAM again.
The bidirectional shift register shifts data
at the falling edge of CL1. During master
mode, this pin-outputs a data transfer
clock with a two times larger cycle than
the internal oscillator (or the cycle of the
external clock) with a duty of 50%.
During slave mode, this pin inputs the
external data transfer clock.

During master mode, pin FLM outputs
the first line marker. During slave mode,
this pin inputs the external data first line
marker. The shift direction of the first
line marker is determined by DUTY and
SHL signal as follows. Set signal DUTY
to high during slave mode. See Table 5.
