8.4.11Optical Module Register Overview

Table 153 through Table 156 “I2C Data Ports 0 - 3 ($0x79F)” on page 222 provide an overview of the Optical Module Registers.

Note: All registers in this section are only applicable to ports that are configured in fiber mode.

Table 153. Optical Module Status Ports 0-3 ($0x799)

Bit	Name	Description	Type1	Default
Register Description: This register provides a means to control and monitor the interface to				0x00000000
the optical modules when a port is used in fiber mode.
31:24	Reserved	Reserved	RO	0x00
23:20	Rx_LOS_3:0	Rx_LOS inputs for Ports 0-3	R	0x0
19:14	Reserved	Reserved		0X00
13:10	Tx_FAULT_3:0	Tx_FAULT inputs for Ports 0-3	R	0x0
9:4	Reserved	Reserved		0X00
3:0	MOD_DEF_3:0	MOD_DEF inputs for Ports 0-3	R	0x0

1. RO = Read Only, No clear on Read; R = Read, Clear on Read; W = Write only; R/W = Read/Write, No clear; R/W/C = Read/Write, Clear on Write

Table 154. Optical Module Control Ports 0 - 3 ($0x79A)

Bit	Name	Description	Type1	Default
Register Description: This register provides access to optical module interrupt enables and				0x00000000
sets the TX_DISABLE output for the ports configured in fiber mode.
31:17	Reserved	Reserved	RO	0x0000
16:13	I2C_port_enable	When set, individually enables the four I2C ports.	R/W	0xf
12	RX_LOS_EN	Enable for RX_LOS_INT operation	R/W	0
		1 = Enabled
11	TX_FAULT_EN	Enable for TX_FAULT_INT operation	R/W	0
		1 = Enabled
10	MOD_DEF_EN	Enable for MOD_DEF_INT operation	R/W	0
		1 = Enabled
9:4	Reserved	Reserved	RO	0X00
3:0	TX_DISABLE_3:0	Tx_DISABLE outputs for Ports 0-3	R/W	0x0

1. RO = Read Only, No clear on Read; R = Read, Clear on Read; W = Write only; R/W = Read/Write, No clear; R/W/C = Read/Write, Clear on Write
