18.0 Register Description
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.
18.51 RECEIVE PORT B PERFORMANCE INTERRUPT ENABLES — 0x7B RBPIE
Type:
Software Lock: No
Reset Value:
This register contains the interrupt enables for the alarms in the RBPA register. Set = interrupt enabled and Clear = interrupt
disabled.
18.52 RECEIVE PORT B REMOTE STATUS AND ALARMS — 0x7C RBRA
Type:
Software Lock: No
Reset Value:
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.
18.53 RECEIVE PORT B REMOTE INTERRUPT ENABLES — 0x7D RBRIE
Type:
Software Lock: No
Reset Value:
This register contains the interrupt enables for the alarms in the RBRB register. Set = interrupt enabled and Clear = interrupt
disabled.
• RBXHEC Receive Port B, Excessive HEC Errors. Set = Number of HEC errors counted in RBHECC is equal to or greater than
• RBXBIP Receive Port B, Excessive BIP Errors. Set = Number of BIP errors counted in RBBIPC is equal to or greater than the
• 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
