INV bit is set to ‘1’. Before the insertion, the generated pattern can be
inverted when the TINV bit is set.
3.27.1.2 Pattern Detector
pattern detector starts to extract the data. The extracted data is used to
re-generate a desired pattern which is selected by the PATS[1:0] bits.

Functional Description
IDT82P2288
Note:
* ID means Indirect Register in the Receive & Transmit Payload Control function blocks.
Three patterns are generated: 2
The selected pattern is generated once there is a transition from ‘0’
A single bit error will be inserted to the generated pattern when the

The extracted data is compared with the re-generated pattern. If the
extracted data coincides with the pattern, the pattern is synchronized
and it will be indicated by the SYNCV bit. In synchronization state, each
mismatched bit will generate a PRGD Bit Error event. This event is
captured by the BERI bit and is forwarded to the Performance Monitor.
An interrupt reported on the INT pin will be enabled by the BERE bit if
the BERI bit is ‘1’. When there are more than 10-bit errors detected in
the fixed 48-bit window, the extracted data is out of synchronization and
it also will be indicated by the SYNCV bit. Any transition (from ‘1’ to ‘0’ or
from ‘0’ to ‘1’) on the SYNCV bit will set the SYNCI bit. An interrupt
reported on the INT pin will be enabled by the SYNCE bit if the SYNCI
bit is ‘1’.
