CYUSB3328: Overcurrent detect input for US port in ACA-Dock mode. If
39
ACA-Dock mode is disabled using Configuration Options on page 17, this pin
must be pulled HIGH using a 10 k to VDD_IO.
Other part numbers: This pin must be pulled HIGH using a 10 k to VDD_IO.
CYUSB3328: VBUS power enable output for US port in ACA-Dock mode. If
ACA-Dock mode is disabled using Configuration Options on page 17, this pin can
31
be left floating if Pin-Strap is not enabled.
Other part numbers: This pin can be left floating if Pin-Strap (Pin# 63) is not
enabled.
This pin is called PWR_SW_POL in pin-strap configuration mode.
