TYPICAL APPLICATIO
N
S
BCLR
PORTD,Y %00100000
This sets the SS* output bit to a logic
low, selecting the LTC1417
Load accumulator A with a null byte for SPI transfer
This writes the byte into the SPI data register and
starts the transfer
This loop waits for the SPI to complete a serial
transfer/exchange by reading the SPI Status Register
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.
Load accumulator A with the current byte of LTC1417 data
that was just received
Transfer the LTC1417’s data to memory
Increment the pointer
#DIN2+1Has the last byte been transferred/exchanged
TRFLP1 If the last byte has not been reached, then proceed to
the next byte for transfer/exchage
PORTD,Y %00100000
This sets the SS* output bit to a logic
high, de-selecting the LTC1417

Load the contents of DIN1 and DIN2 into the double
accumulator D
