Receive data A, B.
These inputs are associated with individual
serial channel data to the SC16C852L receive input circuits, A
through B. The RXx signal will be a logic 1 during reset, idle (no
data), or when not receiving data. During the local loopback mode,
the RXA/RXB input pin is disabled and transmit data is connected
to the UART receive input, internally.
Receive Ready A, B (active LOW).
This function provides the
receive FIFO/RHR status for individual receive channels (A to B).
RXRDYx is primarily intended for monitoring DMA mode 1
transfers for the receive data FIFOs. A logic 0 indicates there is a
receive data to read/upload, that is, receive ready status with one
or more RX characters available in the FIFO/RHR. This pin is a
logic 1 when the FIFO/RHR is empty or when the programmed
trigger level has not been reached. This signal can also be used
for single mode transfers (DMA mode 0).
Transmit data A, B.
These outputs are associated with individual
serial transmit channel data from the SC16C852L. The TXx signal
will be a logic 1 during reset, idle (no data), or when the transmitter
is disabled. During the local loopback mode, the TXA/TXB output
pin is disabled and transmit data is internally connected to the
UART receive input.
Transmit Ready A, B (active LOW).
These outputs provide the
transmit FIFO/THR status for individual transmit channels (A to B).
TXRDYx is primarily intended for monitoring DMA mode 1
transfers for the transmit data FIFOs. An individual channel’s
TXRDYA, TXRDYB buffer ready status is indicated by logic 0, that
is, at lease one location is empty and available in the FIFO or THR.
This pin goes to a logic 1 (DMA mode 1) when there are no more
empty locations in the FIFO or THR. This signal can also be used
for single mode transfers (DMA mode 0).
Power supply input.
Signal and power ground.
Crystal or external clock input.
Functions as a crystal input or as
an external clock input. A crystal can be connected between this
pin and XTAL2 to form an internal oscillator circuit. Alternatively, an
external clock can be connected to this pin to provide custom data
rates (see
Section 6.9 “Programmable baud rate generator”
).
See
Figure 8
.
Output of the crystal oscillator or buffered clock.
(See also
XTAL1.) Crystal oscillator output or buffered clock output. Should
be left open if an external clock is connected to XTAL1.
