How to Input Data
How to Input HD61602 Data
Input data is composed of 8 bits
×
2. Take care that the data transfer is not interrupted, because the first
8-bit data is distinguished from the second one by the sequence only.
If data transfer is interrupted, or at power on, the following two methods can be used to reset the count of
the number of bytes (count of the first and second bytes):
1. Set
&6
and
5(
inputs low (no display data changes).
2. Input 2 or more “1-byte instruction” data in which bit 7 and 6 are 1 (display data may change).
The data input method via data input terminals (
&6
,
:(
, D0 to D7) is similar to that of static RAM such
as HM6116. An access of the LSI can be made through the same bus line as ROM and RAM. When
output ports of a microprocessor are used for an access, refer to the timing specifications and Figure 16.

READY output is indefinite during 12 clocks after the oscillation start at power on (clock:
OSC2 clock).
High pulse should be applied to SYNC terminal when using two or more chips
synchronously.
In the mode in which READY is always available, READY output is in definite while SYNC
is high.
Reset the byte counter after power on.
READY output period is within 3.5 clocks in the mode setting operation and bit
manipulation or within 10.5 clocks when the display data (8 bits) is updated.
Connect a pull-up resister if WE or RE may be floating.
It is not always necessary to follow this example.
