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
is selected 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
pin along with 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
selected by I2C/SPI pin, this pin function is undefined and must
be left as n.c. (not connected).

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 k for 3.3 V, 1.5 k for 2.5 V) must be
connected between this pin and V

UART request to send (active LOW). A logic 0 on the RTS pin
indicates the transmitter has data ready and waiting to send.
Writing a logic 1 in the modem control register MCR[1] will set
this pin to a logic 0, indicating data is available. After a reset this
pin is set to a logic 1. This pin only affects the transmit and
receive operations when auto RTS function is enabled via the
Enhanced Feature Register (EFR[6]) for hardware flow control
operation.
