Here's a stab at it, (untested)

        movlw 0xA0
        movwf FSR
        movlw d'240'
        movwf Count

InLoop  call receive  ; get a byte
        movwf INDF
        incf FSR
        movlw 0xF0
        xorwf FSR,W
        btfss STATUS,Z
        goto UCount

        movlw 0x30
        addwf FSR
        bsf STATUS,IRP ; accesses RP 2 & 3

UCount  decfsz Count
        goto InLoop

        Done...
