6.2.18 LED1 Configuration Defaults (Word 0x1C)
These Flash words specify the hardware defaults for the LEDCTL register fields controlling the LED1
(ACTIVITY indication) output behavior. These words control the LED behavior of the LAN port.
6.2.19 Device Rev ID (Word 0x1E)

Default HW
Mode
Description
15:11 Reserved 0x0 Reserved.
7 LED1 Blink 1b
Initial value of LED1_BLINK field.
0b = Non-blinking.
See Section 8.2.8 and Section 7.5.
6 LED1 Invert 0b
Initial value of LED1_IVRT field.
0b = Active-low output.
See Section 8.2.8 and Section 7.5.
5:4 Reserved 00b Reserved.
3:0 LED1 Mode 0100b
Initial value of the LED1_MODE field specifying what event/state/pattern is
displayed on LED1 (LINK/ACTIVITY) output. A value of 0100b (0x4) indicates the
LINK state when active and ACTIVITY when BLINK.
See Section 8.2.8 and Section 7.5.

(Static) Device Off
Enable
1
1. One single device off mode can be enabled in NVM/iNVM at the same time, either Static or Dynamic Device Off mode.
0b
Enable power down when the DEV_OFF_N pin is asserted. Refer to Section 5.2.6.1
for details.

Dynamic Device
Off Enable
1
0b
Enable Dynamic Power Down
The device dynamically powers down when PCIe is in Dr state and the PHY/SerDes
is not used for manageability or WoL. Refer to Section 5.2.6.2 for details.
13:12 Reserved 00b • Reserved.
11 LAN iSCSI Enable 0b
When set, the LAN class code is set to 0x010000 (SCSI)
When reset, the LAN class code is set to 0x020000 (LAN)
Refer to Section 9.3.6.
10 Reserved 0b Reserved.

wrdn_confg
00b
00b = No copper PHY power down in device off states.
01b = Power Down with energy detect in device off state.
1xb = IEEE power down - coming out of power down is immediate, link needs to be
re-negotiated. This is the recommended NVM setting when the device off feature is
enabled.
7:0 DEVREVID 0x0
Device Revision ID
The actual device revision ID is this Flash value XORed with the hardware default of
Rev ID. For any device version the default value in this field is set to zero unless we
need to overwrite the hardware default. Refer to Section 9.3.5.
