; CROSSBAR REGISTER CONFIGURATION
;
; NOTE: The crossbar register should be configured before any  
; of the digital peripherals are enabled. The pinout of the 
; device is dependent on the crossbar configuration so caution 
; must be exercised when modifying the contents of the XBR0, 
; XBR1, and XBR2 registers. For detailed information on 
; Crossbar Decoder Configuration, refer to Application Note 
; AN001, "Configuring the Port I/O Crossbar Decoder". 
;----------------------------------------------------------------

; Configure the XBRn Registers

	mov XBR0, #000h	; XBAR0: Initial Reset Value
	mov XBR1, #000h	; XBAR1: Initial Reset Value
	mov XBR2, #000h	; XBAR2: Initial Reset Value

; Select Pin I/0

; NOTE: Some peripheral I/O pins can function as either inputs or 
; outputs, depending on the configuration of the peripheral. By default,
; the configuration utility will configure these I/O pins as push-pull 
; outputs.  If the I/O direction changes to input once the peripheral is
; configured, the peripheral hardware will override the PRTnCF register 
; setting and change the pin configuration to input.

; Port configuration (1 = Push Pull Output)
