I am developing a VF3x based for cash register HW. I expected the Ext_POR pin as an external power on reset pin and connected a reset chip's reset signal out to it. In latest document "http://cache.freescale.com/files/microcontrollers/doc/data_sheet/VYBRIDFSERIESEC.pdf?fpsp=1&WT_TYPE=Data%20Sheets&WT_VENDOR=FREESCALE&WT_FILE_FORMAT=pdf&WT_ASSET=Documentation" It is written that this pin is for factory use only, tie it to GND. Should I connect my RESET signal to RESET_B/RESET_OUT pin? or May I still use Ext_POR pin to reset the Vybrid?
