SIO Functional Description
Section 2.6, “GPIO/LED and SIO Configuration,” on page 2-23
more information on the configuration of the GPIO and LED signals.
The LSISASx12 transmits SGIO information on a serial interface to
external logic. The SIO interface has BlinkClkin, BlinkClkout, SioClkin,
Siolkout, SioDout, SioStart, SioEnd, and SioDin signals. SioStart and
SioEnd control the input and output data streams, SioDout and SioDin.
The SIO signals are mapped to the LSISASx12 GPIO/LED signals.
The LSISASx12A provides enhanced SGPIO support which is not
available on the LSISASx12. The enhanced functionality enables
additional data modulation for blink rates and blink patterns. The
LSISASx12A also provides programmable LED/GPIO on/off times.
Configuration of the enhanced SGPIO interface is accomplished through
SMP register write commands.
