Data bus line
Note (1), Note (2)
Note:
In the HD44780, the data can be sent in either 4-bit 2-operation or
8-bit 1-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 - DB, and DBo -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. -DB, when interface data is 8 bits long) is transferred first
and then lower order 4 bits (contents of DBo -DB3 when interface
data is 8 bits long).
(2) When interface data is 8 bits long, data is transferred using 8 data
buses of DBo -DB,.
