The subsystem registers are accessible at Device Address 0x1E using Clause 45 access. For systems that do not support the interface

specified under Clause 45, these registers can be accessed using Clause 22 access via Register 0x0010 and Register 0x0011.

The default value of some of the registers are determined by the value of the hardware configuration pins, which are read just after the

RESET_N pin is deasserted (see the Hardware Configuration Pins section) so that the default operation of the ADIN1300 can be configured in

unmanaged applications. The default values in the registers listed in Table 121 assume that the ADIN1300 is configured with autonegotiation

enabled, all speeds advertised, and the ADIN1300 is not configured to enter software power-down after reset.

SUBSYSTEM REGISTER DETAILS

Subsystem Software Reset Register

Address: 0xFF0C, Reset: 0x0000, Name: GE_SFT_RST

The soft reset register is used to reset the subsystem.

GE_SFT_RST

The subsystem can be reset by setting GE_SFT_RST to 1. The subsystem behavior depends on the setting of the

GE_SFT_RST_CFG_EN register.

0x0

R/W SC

When the GE_SFT_RST_CFG_EN bit is set, the subsystem requests a new set of hardware configuration pin settings

from the chip during the software reset sequence. When GE_SFT_RST_CFG_EN is clear, the previously stored

hardware configuration pin settings are reloaded into the corresponding management registers.

Subsystem Software Reset Configuration Enable Register

Address: 0xFF0D, Reset: 0x0000, Name: GE_SFT_RST_CFG_EN

In the event of a software reset using the GE_SFT_RST bit, the subsystem behavior depends on the setting of this register bit.
