Description
UART clear to send (active LOW). A logic 0
(LOW) on the CTS pin indicates the modem or
data set is ready to accept transmit data from the
SC16IS850L. Status can be tested by reading
MSR[4]. This pin only affect the transmit and
receive operations when Auto-CTS function is
enabled via the Enhanced Feature Register
EFR[7] for hardware flow control operation.
UART transmitter output. During the local
Loopback mode, the TX output pin is disabled
and TX data is internally connected to the UART
RX input.
UART receiver input. During the local Loopback
mode, the RX input pin is disabled and TX data
is connected to the UART RX input internally.
Device hardware reset (active LOW).
Crystal input or external clock input. Functions as
a crystal input or as an external clock input. A
crystal can be connected between XTAL1 and
XTAL2 to form an internal oscillator circuit (see
Figure
connected to this pin.
Crystal output or clock output. (See also XTAL1.)
XTAL2 is used as a crystal oscillator output.
