DESCRIPTION
Change in Receive Trail-Trace Buffer Message Interrupt Sta-
tus:
This RESET-upon-READ bit-field indicates whether or not the
"Change in RxTTB Message" Interrupt has occurred since the
last read of this register.
If this interrupt is enabled, then the DS3/E3 Framer block will
generate an interrupt anytime it receives a Trail-Trace Buffer
Message, that is different from that of the previously received
message.
0 - Indicates that the "Change in Receive TTB Message" Inter-
rupt has NOT occurred since the last read of this register.
1 - Indicates that the "Change in Receive TTB Message" Inter-
rupt has occurred since the last read of this register.
NOTE:
The user can obtain the value of the most recently
received TTB Message by reading out the contents of
the "RxE3 TTB-0" through "RxE3 TTB-15" registers
(Direct Address = 0x111C through 0x112B).
Detection of FEBE Event Interrupt Status:
This RESET-upon-READ bit-field indicates whether or not the
"Detection of FEBE Event" Interrupt has occurred since the last
read of this register.
If this interrupt is enabled, then the DS3/E3 Framer block will
generate an interrupt anytime is detects a FEBE event in the
incoming E3 data-stream.
0 - Indicates that the "Detection of FEBE Event" Interrupt has
NOT occurred since the last read of this register.
1 - Indicates that the "Detection of FEBE Event" Interrupt has
occurred since the last read of this register.
