Thanks to all those who replied both on and off list regarding= powering peripherals with port pins, FETs, and inverters. After= considering the emails I received and checking with Microchip I'm going for port= pin power since the external devices all run off 5 volts and the= current requirements were well under the 25mA per port pin= specification.
