Hi Joe,
I have additional questions about SFL pin.
This pin is input or output. So there is something I don't know how we should handle the SFL pin.
Question 3.
Please tell me the status of SFL pin as following two conditions:
1) After power-on, reset is active.
2) After 1), reset becomes non-active.
On condition 1) and 2), which is the status of SFL pin input or output?, also High or Low?
Question 4.
When we don't use SFL pin, could you tell me how we should handle the pin?
There is a description for unused pins on the datasheet as follows:
"Any other unused digital inputs should be tied to ground. Unused digital output pins should be left floating."
But the SFL pin is input/output pin, so we don't know how we should handle the pin when the pin is not used.
I'm so sorry for many questions.
Thank you.
Best regards.
Tamu
