Hi all
Would you mind if we ask TCA6416A?
<Question1>
On the datasheet Figure32, what does it mean tir?
Does this situation mean Data into port=Data From portm, so finish of read?
<Question2>
On the datasheet Figure32, what is the condtion which INT returns to high?
Is it to read the data which an input ports change state?
Could you let us know the condtion which INT returns to high?
<Question3>
If there is no changes of input ports, does INT port remain high despite of Read/Write?
<Question4>
When the device is reset operation, what does INT operate?
-Power Up Default : input setting
-If there is the difference between Q output of Input Port Resister and actual port inputs, does INT operate?
-Input low during Power on / Reset, does INT operate?
-Until the device are read input setting ports, does INT remain Low? Or, by writting configuration resister, does INT pint returns to High?
Kind regards,
Hirotaka Matsumoto
