--- Inquiry background ---
CY8CMBR3108 does not have a reset terminal.
For example, I want to turn off the power when malfunctioning due to noise.
At this time, I want to turn off the power after dropping pins 14 to 16 to low level at the host.
--------------------------
I want to confirm the output terminal configuration of pins 14 to 16 of CY8CMBR3108.
I understand that pins 14-16 are open drain terminals.
Q1.
Do these pins not output High in the internal settings?
*
I don't think pins 14-16 are open drain and these pins never output high.
I want to make sure that this is correct.
Best Regards,
Harukawa

Hi noha_3407421,
1. Pins 14, 15 and 16 are open drain drives low pin therefore it can not be driven high without an external pull up.
2. Pin 12 can be used as a reset pin during boot up. Make certain that this pin is not grounded during power-up for the device to boot up properly. After boot-up, this I/O functions as indicated by the pin name.
Hope this helps.
