CS/A0

7
I
SPI chip select or I2C-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 I2C-bus configuration is selected by
I2C/SPI pin, this pin along with A1 pin allows user to change the device’s
base address.
To select the device address, please refer to Table 32.
CTSA
2
31
I
UART clear to send (active LOW), channel A. A logic 0 (LOW) on the
CTSA pin indicates the modem or data set is ready to accept transmit
data from the SC16IS752/SC16IS762. Status can be tested by reading
MSR[4]. This pin only affects the transmit and receive operations when
Auto-CTS function is enabled via the Enhanced Features Register
EFR[7] for hardware flow control operation.
CTSB
16
15
I
UART clear to send (active LOW), channel B. A logic 0 on the CTSB pin
indicates the modem or data set is ready to accept transmit data from the
SC16IS752/SC16IS762. Status can be tested by reading MSR[4]. This
pin only affects the transmit and receive operations when Auto-CTS
function is enabled via the Enhanced Features Register EFR[7] for
hardware flow control operation.
I2C/SPI
96
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.
IRQ
15
14
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
for 3.3 V,
1.5 k
for 2.5 V) must be connected between this pin and V
DD.
SI/A1
11
8
I
SPI data input pin or I2C-bus device address select A1. If SPI
configuration is selected by I2C/SPI pin, this is the SPI data input pin. If
I2C-bus configuration is selected by I2C/SPI pin, this pin along with the
A0 pin allows user to change the slave base address. To select the
device address, please refer to Table 32.
SO
12
9
O
SPI data output pin. If SPI configuration is selected by I2C/SPI pin, this is
a 3-stateable output pin. If I2C-bus configuration is selected by the
I2C/SPI pin, this pin is undefined and must be left as not connected.
SCL/SCLK
13
10
I
I2C-bus or SPI input clock.
SDA
14
11
I/O
I2C-bus data input/output, open-drain if I2C-bus configuration is selected
by I2C/SPI pin. If SPI configuration is selected, this is not used and must
be connected to VSS.
