Table Read Program Example

tempreg1 db ?

; temporary register #1 in current page

tempreg2 db ?

; temporary register #2 in current page

mov a,06h

; initialise low table pointer - note that this address is referenced

mov tblp,a

; to the last page or the page that tbhp pointed

mov a,1fh

; initialise high table pointer

mov tbhp,a

; it is not necessary to set tbhp if executing tabrdl

tabrd tempreg1

tabrdl tempreg1

; transfers value in table referenced by table pointer data at program

; memory address “1F06H” transferred to tempreg1 and TBLH

dec tblp

; reduce value of table pointer by one

tabrd tempreg2

tabrdl tempreg2

; transfers value in table referenced by table pointer data at program

; memory address “1F05H” transferred to tempreg2 and TBLH. In this

; example the data “1AH” is transferred to tempreg1 and data “0FH” to

; register tempreg2 while the value “00H” will be transferred to the

; high byte register TBLH

org 1F00h

; sets initial address of program memory

dc 000Ah, 000Bh, 000Ch, 000Dh, 000Eh, 000Fh, 001Ah, 001Bh
