9 / 15 page  DS2167/DS2168 022698 9/15 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.
