4.6.1 Front-blade Interface
The RTM-ATCA-F125 includes an SPI interface between the front-blade service processor and
the RTM FPGA. There is also an active low interrupt line to the front-blade to request service.
4.6.2 SFP/SFP+ Control and Status
The RTM FPGA provides register access to control the following SFP and SFP+ signals:
z
SFP TX_DISABLE
z
SFP RATE_SEL
z
SFP+ RS0/1
The RTM FPGA provides access to the following SFP and SFP+ status signals:
z
SFP MOD_ABS
z
SFP TX_FAULT
z
SFP LOS
z
SFP+ MOD_ABS
z
SFP+ TX_FAULT
z
SFP+ LOS
Each signal can be programmed to cause an interrupt when its state changes.
4.6.3 BCM8747 Control and Status
The RTM FPGA provides register access to the BCM8747 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 BCM8747 status signals:
z
PCMULK
z
PCDRLK
z
PLOSB
z
LASI
