Normal Operation:
A correct QID is generated. No ’BUFER5’ interrupt
should occur indicating an internal queue pointer failure.
1
Test Mode:
The LSB of the QID is inverted to test the QID checking
function. A ’BUFER5’ (Register 46: ISRU, Register 47:
ISRD) interrupt is generated whenever a cell is Read out
out the Cell Buffer RAM.
Note: The respective QID value is stored with each cell
when written to the appropriate queue in the cell
storage RAM. The ABM checks the stored QID
value against the supposed QID when a cell is
read back from the cell storage RAM.
