Description
The UART Input pin provides the UART input to the serial
debugger.
The LED Synchronization Output pin provides a 0.5 Hz
output clock that can drive the LEDSYNCIN pin on other
expanders.
This signal is multiplexed to the SIO interface. Refer to
Section 3.7, “Multiplexed SIO Interface,”
interface signal definitions.
The LED Synchronization Input pin provides an
asynchronous input to the blink pattern generators. All
blink pattern generators restart their blink pattern on the
rising edge of this signal.
This signal is multiplexed to the SIO interface. Refer to
Section 3.7, “Multiplexed SIO Interface,”
interface signal definitions.

This output signal indicates that this module is
currently driving the last bit of serial data on the
SioDout line.
This signal indicates that serial data may be driven
on the SioDout line during the next clock cycle, and
that data can be received on the SioDin line.
In Single originator mode, which is set by the
SioMode bit in the SIO Control register, the SioEnd
signal provides the start signal, and the LSISASx12
does not require an SioStart input.
This signal provides the serial data output line.
This signal provides the serial data input line.
