LPC2148 GPIO Tutorial PINSEL Register. A 32-bit register is used to select the function of the pins in which the user needs it to operate. As I said there are four functions for each pin of the controller, and the first function was GPIO ( General Purpose Input Output ). It means that the pin can either act as an Input or Output with no specific functions. Here is an example of how an embedded system works. It takes the analog/digital input from the user. Examples are Push-button switch, Keypad, Sensor, Touch Screen. Then, it processes the given input. Processing may be calculation or conversion. For example, an ADC (Analog to digital converter) converts a sensor analog input to digital output. VxWorks 7 on zynq ZC702, based on XAPP1258. I followed the XAPP1258 to run VxWorks on ZC702 board and I could run the examples. Now I want to access a register on PL side, so I added it in Vivado at an arbitrary address (0x43C00000) and mapped it the same way as the GPIO_BASE (pg 26) but when I try to access it (using sysOutLong), the PS hangs.
