18.0 Register Description (Continued)
The Receive Port B Performance Alarms register contains information about the error performance of Port B. When set RBXHEC
and RBXBIP will raise an interrupt if the corresponding interrupt enable bits are set.
• RBXHEC Receive Port B, Excessive HEC Errors. Set = Number of HEC errors counted in RBHECC is equal to or greater than
the threshold set in RBHECT. This bit is set when RBHECC = RBHECT and can only be cleared by a read of this register.
• RBXBIP Receive Port B, Excessive BIP Errors. Set = Number of BIP errors counted in RBBIPC is equal to or greater than the
threshold set in RBBIPT. This bit is set when RBBIPC = RBBIPT and can only be cleared by a read of this register.

The Receive Port B Remote Status and Alarms register contains information on the status of the far-end device, which is
connected to Port B. On a local Loss of Signal on Port B, LLOSB alarm, these bits return to their reset values. When set, the
RBRLOSA, RBRLOSB, RBRBA, and RBRDSLL bits will raise an interrupt if the corresponding interrupt enable is set. Also, a
change in value on RBRLOSA, RBRLOSB, RBRDSLL or RBRBA will set the RBRCS bit. When set, the RBRCS bit will raise an
interrupt if the corresponding interrupt enable is set.
• RBRCS Receive Port B, Remote Change of Status at far end device LVDS receive Ports.
• RBRLOSA Receive Port B, Remote Loss Of Signal at far end device LVDS receive Port A.
• RBRLOSB Receive Port B, Remote Loss Of Signal at far end device LVDS receive Port B.
• RBRBA Receive Port B, Remote far end device active receive Port. Set = Port B active and Clear = Port A active. Note that
this bit, if set, will not clear on a read of this register.
• RBRDSLL Receive Port B, Remote far end device active receive port Descrambler Loss of Lock. Set = Out of Lock and Clear
= Lock.
