Serial-3-wire Interface
The serial-3-wire interface (or Serial-to-Parallel Interface)
uses a serial input to shift the data in the register buffer. When
the complete data word is shifted into the register buffer the
data word is loaded into the internal register where it is
decoded. (See
REG_ADDR (3:0); S_DATA (11:0) Data bits REG_DATA
(11:0). When S_EN is asserted the parallel data is loaded into
the internal registers of the IBIS5-A-1300. The maximum
tested frequency of S_DATA is 2.5 MHz.)

Serial-2-wire Interface
The serial-2-wire interface is a unidirectional interface (only
register value can be written to the sensor; nothing can be read
out). Therefore, the R/W_N bit (bit 8) is ignored internally. An
acknowledge pulse is asserted each time a data word is
received successfully. The maximum tested frequency of
S_DATA is 2.5 MHz. (See
Address bits REG_ADDR (3:0); S_DATA (11:0) Data bits
REG_DATA (11:0)).
