I want to use A0 thru A10 as the address bus, and then use the remaining A pins as GPIO.</DIV><DIV>&nbsp;</DIV><DIV>Can I set this up in PE? When I turn on the address bus, PE conflicts with the BitIO beans that I setup for the remaining pins. Can I tell PE that I only want to use certain address and data lines for the external bus?</DIV><DIV>&nbsp;</DIV><DIV>Thanks,</DIV><DIV>Tim</DIV><DIV>&nbsp;</DIV></BODY></HTML> Fri, 05 May 2006 21:59:31 GMT https://community.nxp.com/t5/S12-MagniV-Microcontrollers/Sharing-I-O-and-External-Bus-using-Processor-Expert/m-p/134867#M2123 ETCTim 2006-05-05T21:59:31Z Re: Sharing I/O and External Bus using Processor Expert https://community.nxp.com/t5/S12-MagniV-Microcontrollers/Sharing-I-O-and-External-Bus-using-Processor-Expert/m-p/134868#M2124 <HTML><HEAD></HEAD><BODY>If it's like the MC9S12, you could only configure the port as GPIO (then bitbang it), or configure the whole port to be an address bus (expanded i/o).</BODY></HTML> Sat, 06 May 2006 01:03:19 GMT https://community.nxp.com/t5/S12-MagniV-Microcontrollers/Sharing-I-O-and-External-Bus-using-Processor-Expert/m-p/134868#M2124 imajeff 2006-05-06T01:03:19Z Re: Sharing I/O and External Bus using Processor Expert https://community.nxp.com/t5/S12-MagniV-Microcontrollers/Sharing-I-O-and-External-Bus-using-Processor-Expert/m-p/134869#M2125 <HTML><HEAD></HEAD><BODY><DIV></DIV><DIV>The current version of Processor Expert allows only to enable/disable the whole external bus.
