“1” enables this interrupt. Setting this bit-field to “0” disables this interrupt. For more information on this interrupt,
please see Section 7.1.2.9.5.
Bit 1—Framing Byte Error Interrupt Enable
This “Read/Write” bit-field allows the user to enable or disable the “Framing Byte Error” interrupt. Setting this bit-
field to “1” enables this interrupt. Setting this bit-field to “0” disables this interrupt. For more information on this inter-
rupt, please see Section 7.1.2.9.12.
Bit 0—Receive Payload Type Mismatch Interrupt Enable
This “Read/Write” bit-field allows the user to enable or disable the “Receive Payload Type Mismatch” interrupt. Set-
ting this bit-field to “1” enables this interrupt. Setting this bit-field to “0” disables this interrupt. For more information
on this interrupt, please see Section 7.1.2.9.9.
3.3.2.20 Rx E3 Interrupt Status Register-1
Bit 4—COFA (Change of Frame Alignment) Interrupt Status
This “Reset-upon-Read” bit-field will be set to “1” if the “Change of Frame Alignment” interrupt has occurred since
the last read of this register.
The Receive E3 Framer will generate the “Change of Frame Alignment” interrupt if it has detected a change in
frame alignment; in the incoming E3 frames.
Bit 3—OOF (Receive E3 Framer) Interrupt Status
This “Reset Upon Read” bit-field is set to “1” if the Receive E3 Framer has detected a “Change in the Out-of-Frame (OOF)
Condition”, since the last time this register was read. Therefore, this bit-field will be asserted under either of the follow-
ing two conditions:
1.
When the Receive E3 Framer has detected the appropriate conditions to declare an “OOF” Condition.
2.
When the Receive E3 Framer has transitioned from the “OOF” Condition (Frame Acquisition Mode) into the “In-Frame”
Condition (Frame Maintenance mode).
For more information of the OOF Condition, please see Section 7.1.2.2.1.
Bit 2—LOF (Loss of Frame) Interrupt Status
This “Reset-upon-Read” bit-field will be set to “1” if a “Change in LOF Condition” interrupt has occurred since the last
