POST OFFICE BOX 655303
DALLAS, TEXAS 75265
APPLICATION INFORMATION
CLR
T1
; transmit it – set FS low
MOV
SBUF,A
; send it out the serial port
INC
R7
; increment the pointer in R7
MOV
A,R7
; to get the next byte from the table
MOVC
A,@A+DPTR
; which is the lsb of this sample, now in ACC
A_MSB_TX:
JNB
TI,A_MSB_TX
; wait for transmit to complete
CLR
TI
; clear for new transmit
MOV
SBUF,A
; 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
MOV
A,R7
; pointer in R7
ADD
A,#0FH
; add 15 – already done one INC
ANL
A,#03FH
; wrap back round to 0 if > 64
MOV
R7,A
; pointer back in R7
MOVC
A,@A+DPTR
; get DAC C msb from the table
ORL
A,#01H
; set control bits to DAC C address
A_LSB_TX:
JNB
TI,A_LSB_TX
; wait for DAC A lsb transmit to complete
SETB
T1
; toggle FS
CLR T1
CLR
TI
; clear for new transmit
MOV
SBUF,A
; and send out the msb of DAC C
INC
R7
; increment the pointer in R7
MOV
A,R7
; to get the next byte from the table

A,@A+DPTR
; which is the lsb of this sample, now in ACC
C_MSB_TX:
JNB
TI,C_MSB_TX
; wait for transmit to complete
CLR
TI
; clear for new transmit
MOV
SBUF,A
; and send out the lsb of DAC C
; DAC B next
; DAC B codes should be taken from 16 bytes (8 samples) further on
; in the sine table – this gives an inverted sine function
MOV
A,R7
; pointer in R7
ADD
A,#0FH
; add 15 – already done one INC
ANL
A,#03FH
; wrap back round to 0 if > 64
MOV
R7,A
; pointer back in R7
MOVC
A,@A+DPTR
; get DAC B msb from the table
ORL
A,#02H
; set control bits to DAC B address
C_LSB_TX:
JNB

; wait for DAC C lsb transmit to complete
SETB
T1
; toggle FS
CLR
