ACC
CLR
T0
; set CSB low

T1
; set FS low
; The signal to be output on the dac is a sine function. One cycle of a sine wave is
; held in a table @ sinevals as 32 samples of msb, lsb pairs (64 bytes). The pointer,
; rolling_ptr, rolls round the table of samples incrementing by 2 bytes (1 sample) on
; each interrupt (at the end of this routine).
MOV
DPTR,#sinevals
; set DPTR to the start of the table of sine signal values
MOV
A,rolling_ptr
; ACC loaded with the pointer into the sine table
MOVC
A,@A+DPTR
; get msb from the table
ORL
A, #00H
; set control bits
MOV
SBUF,A
; send out msb of data word
MOV A,rolling_ptr ; move rolling pointer in to ACC
INC
A
; increment ACC holding the rolling pointer
MOVC
A,@A+DPTR
; which is the lsb of this sample, now in ACC
MSB_TX:
JNB
TI, MSB_TX
; wait for transmit to complete
CLR
TI
; clear for new transmit
MOV
SBUF,A
; and send out the lsb
LSB_TX:
JNB
TI, LSB_TX
; wait for lsb transmit to complete
SETB
T1
; set FS = 1
CLR
TI
; clear for new transmit
MOV
A,rolling_ptr
; load ACC with rolling pointer
INC
A
; increment the ACC twice, to get next sample
INC
A
ANL
A,#03FH
; wrap back round to 0 if >64
MOV
rolling_ptr,A
; move value held in ACC back to the rolling pointer
SETB
T0
