"Maximum number of pins exceeded" on PSoC 4 SSOP
I'm building a design based on the CY8C4245PVI-482 28-SSOP. When I add another pin, taking the pin count up to 21 in the pin selector, I get the error message "Resource limit: Maximum number of Pins exceeded (max=22, needed=23)". I'm not out of physical pins - all the pins I'm using are assigned to physical pins - and I even have 1 unused pin beside the debug pins.
Where are these 2 ghost pins coming from, why am I getting this error, and how can I eliminate it?
