Here is my RE3 test program.  I copy PORTE to PORTB.  PORTB is 0V, even
though the (MCLR-compatible) button on pin 1 of the PIC is pulling it up.


        include "p18f2320.inc"
        __CONFIG    _CONFIG1H, _IESO_OFF_1H & _INTIO2_OSC_1H
        __CONFIG    _CONFIG2L, _BOR_OFF_2L & _BORV_45_2L & _PWRT_ON_2L
        __CONFIG    _CONFIG2H, _WDT_OFF_2H & _WDTPS_128_2H
        __CONFIG    _CONFIG3H, _CCP2MX_ON_3H & _MCLRE_OFF_3H
        __CONFIG    _CONFIG4L, _STVR_ON_4L & _LVP_OFF_4L & _DEBUG_OFF_4L
        __CONFIG    _CONFIG5L, _CP0_OFF_5L & _CP1_OFF_5L & _CP2_OFF_5L & _CP3_OFF_5L
        __CONFIG    _CONFIG5H, _CPB_OFF_5H & _CPD_OFF_5H
        __CONFIG    _CONFIG6L, _WRT0_OFF_6L & _WRT1_OFF_6L & _WRT2_OFF_6L & _WRT3_OFF_6L
        __CONFIG    _CONFIG6H, _WRTC_OFF_6H & _WRTB_OFF_6H & _WRTD_OFF_6H
        __CONFIG    _CONFIG7L, _EBTR0_OFF_7L & _EBTR1_OFF_7L & _EBTR2_OFF_7L & _EBTR3_OFF_7L
        __CONFIG    _CONFIG7H, _EBTRB_OFF_7H
