Type Description
-
power supply
I
SPI chip select or I
2
C-bus device address select A0. If SPI
configuration is selected by I2C/SPI pin, this pin is the SPI chip select
pin (Schmitt-trigger, active LOW). If I
2
C-bus configuration is selected
by I2C/SPI pin, this pin along with A1 pin allows user to change the
device’s base address.
I
SPI data input pin or I
2
C-bus device address select A1. If SPI
configuration is selected by I2C/SPI pin, this is the SPI data input pin.
If I
2
C-bus configuration 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 28
.
O
SPI data output pin. If SPI configuration is selected by I2C/SPI pin,
this is a 3-stateable output pin. If I
2
C-bus configuration is selected by
I2C/SPI pin, this pin function is undefined and must be left as n.c. (not
connected).
I
I
2
C-bus or SPI input clock.
I/O
I
2
C-bus data input/output, open-drain if I
2
C-bus configuration is
selected by I2C/SPI pin. If SPI configuration is selected then this pin
is an undefined pin and must be connected to V
SS
.
O
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
Ω
for 3.3 V, 1.5 k
Ω
for 2.5 V) must be connected between this pin and
V
DD
.
I
I
2
C-bus or SPI interface select. I
2
C-bus interface is selected if this pin
is at logic HIGH. SPI interface is selected if this pin is at logic LOW.
