Control Interface
LP5520 supports two different interface modes:
SPI interface (4 wire, serial)
I
2
C compatible interface (2 wire, serial)
User can define the serial interface by IF_SEL pin. IF_SEL =
0 selects the I
2
C mode.

SPI Interface
LP5520 is compatible with SPI serial bus specification and it
operates as a slave. The transmission consists of 16-bit Write
and Read Cycles. One cycle consists of 7 Address bits, 1
Read/Write (RW) bit and 8 Data bits. RW bit high state defines
a Write Cycle and low defines a Read Cycle. SO output is
normally in high-impedance state and it is active only when
Data is sent out during a Read Cycle. The Address and Data
are transmitted MSB first. The Slave Select signal SS must
be low during the Cycle transmission. SS resets the interface
when high and it has to be taken high between successive
Cycles. Data is clocked in on the rising edge of the SCK clock
signal, while data is clocked out on the falling edge of SCK.
