Description
The Cable Detection pins can be configured to detect the
presence of a cable on the associated phy. These pins
can also be configured as activity LEDs, fault LEDs, status
LEDs, or independent GPIO signals.
The Activity LED pins can be configured to indicate serial
port activity by driving an LED. These pins can also be
configured as cable detection LEDs, fault LEDs, status
LEDs, or independent GPIO signals.
The Fault LED pins can be configured to indicate a serial
port fault by driving an LED. These pins can also be
configured as cable detection LEDs, activity LEDs, status
LEDs, or independent GPIO signals.
The Status LED pins can be configured to indicate disk
drive activity by driving an LED. These pins can also be
configured as cable detection LEDs, activity LEDs, fault
LEDs, or independent GPIO signals.
LED_STATUS[11:6]/ are multiplexed to the SIO interface.
Refer to
SIO interface signal definitions.
Asserting the Reset pin (which is an active LOW signal)
forces the chip into a Power-On-Reset (POR) state.
The Clock pin provides 75 MHz clock for the internal
control logic.
Refer to SEN S11054: LSISASx12 Design Considerations
(DB05-000116-xx) for information concerning this signal.
The General Purpose Input/Output (GPIO) pins provide
general purpose inputs and/or outputs.
The UART Output pin provides the UART output from the
serial debugger.
