TYPICAL APPLICATIO S
U
**********************************
* The next short loop waits for the
*
* LTC2410's conversion to finish before *
* starting the SPI data transfer
*
**********************************
*
CONVEND LDAA
PORTD
Retrieve the contents of port D
ANDA
#%00000100
Look at bit 2
*
Bit 2 = Hi; the LTC2410's conversion is not
*
complete
*
Bit 2 = Lo; the LTC2410's conversion is complete
BNE
CONVEND
Branch to the loop's beginning while bit 2 remains
high
*
********************
* The SPI data transfer *
********************
*
TRFLP1
LDAA
#$0
Load accumulator A with a null byte for SPI transfer
STAA
SPDR
This writes the byte in the SPI data register and starts
*
the transfer
WAIT1
LDAA
SPSR
This loop waits for the SPI to complete a serial
transfer/exchange by reading the SPI Status Register
BPL
WAIT1
The SPIF (SPI transfer complete flag) bit is the SPSR's MSB
*
and is set to one at the end of an SPI transfer. The branch
*
will occur while SPIF is a zero.
LDAA
SPDR
Load accumulator A with the current byte of LTC2410 data
that was just received
STAA
0,X
Transfer the LTC2410's data to memory
INX
Increment the pointer
CPX
#DIN4+1 Has the last byte been transferred/exchanged?
BNE
TRFLP1
If the last byte has not been reached, then proceed to the
*
next byte for transfer/exchange
BSET
PORTD,Y %00100000 This sets the SS* output bit to a logic high,
*
de-selecting the LTC2410
PULA
Restore the A register
PULY
Restore the Y register
PULX
Restore the X register
RTS
