topic imx31 hardware interface - GPIOs in i.MX Processors https://community.nxp.com/t5/i-MX-Processors/imx31-hardware-interface-GPIOs/m-p/142042#M14 <HTML><HEAD></HEAD><BODY><DIV></DIV>I am designing a system architecture with the imx31 while using the ADS as a reference. I am looking for a description of all the GPIO that I can have available to me through the functional multiplexing. Basically I need to know what GPIO I have available to me for interrupts. The documentation talks about having 32 GPIO through the GPIO module, but then the functional multiplexing and pinout charts show only 9 GPIO available (this seems very low), and anymore I cannot tell if they exist through multiplexing or not. Does anyone know how many independent GPIO I can use specifically for general purpose pins? Any help would be appreciated.</BODY></HTML> Fri, 03 Aug 2007 03:37:08 GMT Olson 2007-08-03T03:37:08Z imx31 hardware interface - GPIOs https://community.nxp.com/t5/i-MX-Processors/imx31-hardware-interface-GPIOs/m-p/142042#M14 <HTML><HEAD></HEAD><BODY><DIV></DIV>I am designing a system architecture with the imx31 while using the ADS as a reference.
