They are configured as a GPIO after reset in this mode (MA=0). The best way is to use ProcessorExpert tool for configuration. The CPU bean provides settings of the external bus and PE can help you very well.</BODY></HTML> Wed, 30 Aug 2006 12:42:41 GMT https://community.nxp.com/t5/Other-NXP-Products/DSP-56F8367-external-memory-access/m-p/125521#M14 marvin 2006-08-30T12:42:41Z
