Data Sheet U17848EJ3V0DS
Remote-control transmitter (56 keys accommodated, mode selection switch accommodated)
Data can be read from the K
I/O0
to K
I/O7
pins by connecting a pull-up resistor of approx. 50 k
and a switch
to these pins (which then become high level when the switch is on and low level when off). Set the K
I/O0
to
K
I/O7
pins to input mode at this time. Reading data from these pins enables multiple output data to be obtained
for the same key input.
A pull-up resistor can be connected to any of pins K
I/O0
to K
I/O7
(the figure below shows an example of when
a pull-up resistor is connected to the K
I/O5
pin).
