I
I2C-bus or SPI interface select. I2C-bus interface is selected if this
pin is at logic HIGH. SPI interface is selected if this pin is at logic
LOW.
CS/A0
5
I
SPI chip select or I2C-bus device address select A0. If SPI
conguration is selected by I2C/SPI pin, this pin is the SPI chip
select pin (Schmitt trigger, active LOW). If I2C-bus conguration
is selected by I2C/SPI pin, this pin along with A1 pin allows user
to change the device’s base address.
SI/A1
6
I
SPI data input pin or I2C-bus device address select A1. If SPI
conguration is selected by I2C/SPI pin, this is the SPI data input
pin. If I2C-bus conguration is selected by I2C/SPI pin, this pin
along with A0 pin allows user to change the device’s base
address. To select the device address, please refer to Table 11.
SO
7
O
SPI data output pin. If SPI conguration is selected by I2C/SPI
pin, this is a 3-stateable output pin. If I2C-bus conguration is
selected by I2C/SPI pin, this pin function is undened and must
be left as n.c. (not connected).
SCL/SCLK
8
I
I2C-bus or SPI input clock.
SDA
9
I/O
I2C-bus data input/output, open-drain if I2C-bus conguration is
selected by I2C/SPI pin. If SPI conguration is selected then this
pin is an undened pin and must be connected to VSS.
