A,R7
A,@A+DPTR
; increment the pointer in R7
; to get the next byte from the table

SBUF,A
; wait for transmit to complete
; clear for new transmit
; and send out the lsb of DAC A
; DAC C next
; DAC C codes should be taken from 16 bytes (8 samples) further on
; in the sine table – this gives a cosine function
