All data transfers are terminated if the CS input transitions high. Port control logic is disabled and SDO is
tri-stated when CS is high.
DATA I/O
Following the eight SCLK cycles that input an address/ command byte to write, a data byte is strobed into
the addressed register on the rising edges of the next eight SCLK cycles. Following an address/command
word to read, contents of the selected register are output on the falling edges of the next eight SCLK
cycles. The SDO pin is tri-stated during device write and may be tied to SDI in applications where the
host processor has a bi-directional I/O pin.
BURST MODE
The burst mode allows all onboard registers to be consecutively read and written by the host processor. A
burst read is used to poll all registers; RSR contents will be unaffected. This feature minimizes device
initialization time on power-up or system reset. Burst mode is initiated when ACB.7 is set and the address
nibble is 0000. Burst is terminated by a low-high transition on CS .
