Test BIP-8 Supervision
0
Normal Operation:
BIP-8 for cell protection is generated normally. No ’BIP8ER’
interrupt should occur indicating a cell storage failure.
1
Test Mode:
Least Significant Bit (LSB) of BIP-8 is inverted to test BIP-8
checking function. A ’BIP8ER’ (Register 115: ISRU,
Register 116: ISRD) interrupt is generated whenever a cell
is Read out of the Cell Buffer RAM.
Test Queue ID Supervision
(see “Cell Queue Supervision” on Page 95)
0
Normal Operation:
A correct QID is generated. No ’BUFER4’ interrupt should
occur indicating an internal queue pointer failure.
