SERIAL PORT WRITE
All port writes are initiated by driving CS low and termi-
nated when CS returns high. Data is sampled on the ris-
ing edge of SCLK and must be written to the device LSB
first. Writes to the device may be two bytes (address/
command and control) or four bytes (address/com-
mand, control, input timeslot and output timeslot) in
length. Writes should be terminated on byte boundaries
to insure data integrity. PCM and ADPCM outputs will
tristate during register updates.
