Dual UART with I
SPI chip select or I
is selected by I2C/SPI pin, this pin is the SPI chip select pin
(Schmitt-trigger active LOW). If I
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
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.
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.
I
at logic HIGH. SPI interface is selected if this pin is at logic LOW.
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
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 slave 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 is undefined and must be left as not connected.
