Problem of Pins Input
On my own breadboard[Cy8C3246AXA], GPIO Read has a problem.
It is a 4bit program Sw, connect to P5-P5
Pins driive mode is Resistive pull up, initial:HIgh, Max voltage:5V
If program digit is ONE, port register might be 0xE0.
Actually, measured voltage is 0V,0,0,5V
But always 0x00 was red, whichever program digit is.
I had attached the project.
