This works when simulated with MPLAB.

Some addresses like 0x1B forced MPLAB to complain so I used the
Mnemonics for them.

STEE  bsf    PORTB,LED
      bsf    STATUS,RP0     ; <<<<  changed from bcf
      bcf    STATUS,RP1
      movlw  0x00
      movwf  EEADR          ; <<< MPLAB complained about 0x1B
      movlw  0x53
      movwf  EEDATA         ; << MPLAB complained
      bcf    STATUS,RP0     ; <<<<<<<< added
      bcf    PIR1,EEIF
      bsf    STATUS,RP0

WRITE bcf    INTCON,GIE
      bsf    EECON1,0x2     ; eecon1,wren
      movlw  0x55
      movwf  EECON2         ; eecon2
      movlw  0xAA
      movwf  EECON2         ; eecon2
      bsf    EECON1,0x1     ; eecon1,wr
      bcf STATUS,RP0        ; <<<<< added = RAM Pg 0 now

WREND btfss  PIR1,EEIF
      goto   WREND

      bcf    PIR1,EEIF
      bsf    STATUS,RP0     ; <<<<<< added = RAM Pg 1 now
      bcf    EECON1,0x2     ; eecon1,wren
      bcf    STATUS,RP0
      ; <<<<< deleted - bcf    status,rp1
      bcf    PORTB,LED

ENDWR   goto   ENDWR
