Functional Description
Functional Description
4.8.2 SFP/SFP+/QSFP+ Control and Status
The RTM FPGA provides register access to control the following SFP and SFP+ signals:

SFP TX_DISABLE

SFP RATE_SEL

SFP+ RS0/1 (tied together)
The RTM FPGA provides access to the following SFP, SFP+, and QSFP+ signals:

SFP MOD_ABS

SFP TX_FAULT

SFP LOS

SFP+ MOD_ABS

SFP+ TX_FAULT

SFP+ LOS

QSFP+ MODPRS#

QSFP+ INT#

QSFP+ LPMODE
Each signal can be programmed to cause an interrupt when its state changes.
4.8.3 BCM8727 Control and Status
The RTM FPGA provides register access to the BCM8727 TXONOFF signals which allow
the SFP+ transmitters to be disabled as well as putting the PHYs into a low-power mode.
The RTM FGPA provides access to the following BCM8727 status signals:

PCMULK

PCDRLK

PLOSB

LASI
Each signal can be programmed to cause an interrupt when its state changes.
