power supply
SPI chip select or I
configuration is selected by I2C/SPI pin, this pin is the SPI chip select
pin (Schmitt-trigger, active LOW). If I
by I2C/SPI pin, this pin along with A1 pin allows user to change the
device’s base address.
SPI data input pin or I
configuration is selected by I2C/SPI pin, this is the SPI data input pin.
If I
A0 pin allows user to change the device’s base address. To select the
device address, please refer to
SPI data output pin. If SPI configuration is selected by I2C/SPI pin,
this is a 3-stateable output pin. If I
I2C/SPI pin, this pin function is undefined and must be left as n.c. (not
connected).
I
I
selected by I2C/SPI pin. If SPI configuration is selected then this pin
is an undefined pin and must be connected to V
Interrupt (open-drain, active LOW). Interrupt is enabled when
interrupt sources are enabled in the Interrupt Enable Register (IER).
Interrupt conditions include: change of state of the input pins, receiver
errors, available receiver buffer data, available transmit buffer space,
or when a modem status flag is detected. An external resistor (1 kΩ
for 3.3 V, 1.5 kΩ for 2.5 V) must be connected between this pin and
V
