Hello,
I want to know about the write operation to the TCA9539.
■Example 1
Write 1 byte(Specify the output port 1, write 1 byte)
⇒ It's written in output port 1.
■Example 2
Write two bytes(Specify the output port 0, write two bytes)
⇒ It's written to the ports 0 and 1.
■Example 3
Write two bytes(Specify the output port 1, write two bytes)
⇒ 【Question】In this case, what data is written in the "???".
Best regards,
Seishin
