UNO setting up SPI for LTC6804

hello,

http://cds.linear.com/docs/en/datasheet/680412f.pdf
on page 41 of datasheet says:

quote

data link layer
all data transfers on ltc6804 occur in byte groups.
every byte consists of 8 bits. bytes transferred with
themost significant bit (msb) first. csbmustremain low
forthe entire duration of command sequence, including
betweenacommandbyteandsubsequentdata. onawrite
command, data latched in on rising edge of csb.

and on page 35

quote

timing
the 4-wire serial port configured operate in spi
systemusingcpha = 1 andcpol = 1. consequently, data
on sdimust stable during rising edge of sck. the
timing depicted in figure 15. maximum data rate
is 1mbps.

is correct setup ?

code: [select]

spi.setbitorder(msbfirst);
spi.setclockdivider(spi_clock_div32); // should fast enough
spi.setdatamode(spi_mode3);

how calculate data rate mhz ? assuming means can send 10^6 bytes in 1 second 1mbps = 8mhz ?

sidenote: http://arduino.cc/de/reference/spiend pull ss down again?

first check datasheet - 5k pull resistor needed on 1 of spi pins.

secondly spi transfers begin bringing cs low, transfering number of bytes,
set cs high again.

for bus speed mhz wire speed, bits per second, not bytes.  1mhz means
a 1mhz sclk (8 per byte transferred).
