• Lead Free Status / Rohs Status: Compliant

18.0 Register Description
The Receive Port A Performance Alarms register contains information about the error performance of Port A. When set RAXHEC
and RAXBIP will raise an interrupt if the corresponding interrupt enable bits are set.
18.32 RECEIVE PORT A PERFORMANCE INTERRUPT ENABLES — 0x3B RAPIE
Type:
Software Lock: No
Reset Value:
This register contains the interrupt enables for the alarms in the RAPA register. Set = interrupt enabled and Clear = interrupt
disabled.
18.33 RECEIVE PORT A REMOTE STATUS AND ALARMS — 0x3C RARA
Type:
Software Lock: No
Reset Value:
The Receive Port A Remote Status and Alarms register contains information on the status of the far-end device, which is
connected to Port A. On a local Loss of Signal on Port A, LLOSA alarm, these bits return to their reset values. When set, the
RARLOSA, RARLOSB, RARBA, and RARDSLL bits will raise an interrupt if the corresponding interrupt enable is set. Also, a
change in value on RARLOSA, RARLOSB, RARDSLL or RARBA will set the RARCS bit. When set, the RARCS bit will raise an
interrupt if the corresponding interrupt enable is set.
18.34 RECEIVE PORT A REMOTE INTERRUPT ENABLES — 0x3D RARIE
Type:
Software Lock: No
Reset Value:
This register contains the interrupt enables for the alarms in the RARA register. Set = interrupt enabled and Clear = interrupt
disabled.
• RAXHEC Receive Port A, Excessive HEC Errors. Set = Number of HEC errors counted in RAHECC is equal to or greater than
