;
transfers value in table referenced by table pointer
; to tempregl
data at prog. memory address "7F06" transferred to
;
; tempreg1 and TBLH
; reduce value of table pointer by one
dec tblp
tabrdl
;
transfers value in table referenced by table pointer
; to tempreg2
data at prog.memory address "7F06" transferred to
; tempreg2 and TBLH
in this example the data "1AH" is transferred to
; tempreg1 and data "0FH" to register tempreg2
the value "00H" will be transferred to the high byt
;
;
;
; register TBLH
