(b4, T1/J1-061H) is logic 1 and the BEI (b2, T1/J1-061H) is logic 0, the
pattern detector is in synchronization state.
then the configuration is shown in Table 60.
- Example For Testing T1/J1 System Backplane Integrity
T1/J1-00FH) should be set to logic 1 and the other registers are set as
above. Then the PRGD can be used to test the system backplane integ-
rity.
Operation
Table 60: Error Insertion
Then set the TEST in RPLC Payload Control register for CH2, CH4 and CH5.
The process is:
Then write 00H into the 06CH register to update the error counter registers.
Then read the registers from 06CH to 06FH to check the error numbers.
After the above setting, read the 061H register twice. If the SYNCV
