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 bidi-
rectional I/O pin.
BURST MODE
The burst mode allows all onboard registers to be con-
secutively 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 initializa-
tion time on power-up or system reset. Burst mode is ini-
tiated when ACB.7 is set and the address nibble is 0000.
Burst is terminated by a low-high transition on CS.
