bit/serial output
data
When 8-bit bus mode, used as lowest bi-
directional data bit. During 4-bit bus
mode, open this pin.
When serial mode, used as serial data
output pin. If not in read operation, open
this pin.
Data bus 1-7
Input.Output
When 8-bit bus mode, used as low order
bi-directional data bus.
During 4-bit bus mode or serial mode,
open these pins.
When 8-bit bus mode, used as high
order bi-directional data bus. In case of
4-bit bus mode, used as both high and
low order. DB7 used for busy flag output.
During serial mode, open these pins.
