Sa6 Block Interrupt Status
This READ ONLY bit-field Indicates whether or not the SA 6 block
has an interrupt request awaiting service.
0 - Reading a ‘0’ indicates no outstanding SA 6 block interrupt
request is awaiting service
1 - Reading a ‘1’ indicates the SA 6 block has an interrupt request
awaiting service. Interrupt Service routine should branch to the inter-
rupt source and read the SA6 block Interrupt Status register
(address 0xnB0C) to clear the interrupt
N
OTE
: This bit-field will be reset to 0 after the microprocessor has
performed a read to the SA6 Interrupt Status Register

Loopback Code Block Interrupt Status
This READ ONLY bit-field indicates whether or not the Loopback
Code block has an interrupt request awaiting service.
0 - Reading a ‘0’ indicates no outstanding Loopback Code Block
interrupt request is awaiting service
1 - Reading a ‘1’ indicates the Loopback Code block has an interrupt
request awaiting service. Interrupt Service routine should branch to
the interrupt source and read the Loopback Code Interrupt Status
register (address 0xnB0A) to clear the interrupt
N
OTE
: This bit-field will be reset to 0 after the microprocessor has
performed a read to the Loopback Code Interrupt Status Register.

Loss of Recovered Clock Interrupt Status
This READ-Upon-Read bit-field indicates whether or not the framer
has experienced a Loss of Recovered Clock interrupt since last read
of this register.
0 = Reading a ‘0’ indicates Loss of Recovered Clock interrupt has
not occurred since last read of this register
1 = Reading a ‘1’ indicates Loss of Recovered Clock interrupt has
occurred since last read of this register.

One Second Interrupt Status
This Reset-Upon-Read bit-field indicates whether or not the framer
has experienced a One Second interrupt since the last read of this
register.
0 = Reading a ‘0’ indicates One Second interrupt has not occurred
since the last read of this register
1 = Reading a ‘1’ indicates One Second interrupt has occurred since
the last read of this register
