1.4.8 Software-Definable Pins (SDP) Interface (General-Purpose I/O)
The I210 has four software-defined pins (SDP pins) that can be used for IEEE1588 auxiliary device
connections, enable/disable of the device, and for other miscellaneous hardware or software-control
purposes. These pins can be individually configurable to act as either standard inputs, General-Purpose
Interrupt (GPI) inputs or output pins (refer to Section 6.2.21, Section 8.2.1 and Section 8.2.3), as well
as the default value of all pins configured as outputs. Information on SDP usage can be found in
Section 3.5 and Section 7.8.3.3. Refer to Section 2.3.7 for pin description of this interface.
1.4.9 LED Interface
The I210 implements three output drivers intended for driving external LED circuits. Each of the three
LED outputs can be individually configured to select the particular event, state, or activity, which is
indicated on that output. In addition, each LED can be individually configured for output polarity as well
as for blinking versus a non-blinking (steady-state) indication.
The configuration for LED outputs is specified via the LEDCTL register. Furthermore, the hardware-
default configuration for all LED outputs can be specified via Flash fields (refer to Section 6.2.18 and
Section 6.2.20), thereby supporting LED displays configurable to a particular OEM preference.
Refer to Section 2.3.6 for full pin description of this interface.
Refer to Section 7.5 for more detailed description of LED behavior.
