Note (1), Note (2)
Note:
In the HD44780, the data can be sent in either 4-bit 2-operation or
8-bit l-operation so that it can interface to both 4 and 8 bit MPU's.
(1) When interface data is 4 bits long, data is transferred using only 4
buses of DB4 ~ DB7 and DB. ~DB3 are not used. Data transfer
between the HD44780 and the MPU completes when 4-bit data is
transferred twice. Data of the higher order 4 bits (contents of
DB. ~DB7 when interface data is 8 bits long) is transferred first
and then lower order 4 bits (contents of DB. -DB3 when interface
data is 8 bits long).
(2) When interface data is 8 bits long, data is transferred using 8 data
buses of DB. ~DB7 .

Note:
(1) 80 ~ E7 are described in hexidecimal for DD RAM address.
(2) The set to HD44780 are "N = "1 ", F = "0" (2 lines 5 x 7 + cursol)."
(3) DD RAM address is no series in Iine. Address set is necessary to
change the lines.
. (4) Circuit is equal to 40 characters by 2 lines type.
(5) In case of executing shift, first line and third line are shifted con-
tinuously, also second line and fourth line. Therefore it happens
that display of third line is transfered to first line.
