Field (Bits)
Description
QE_RX_CH_COUNT_NEG
(6)
1
A Rx Channel Count Depth is negative. This is a non-recoverable state
for the device. The device should be reset and reinitialized.
A Rx Channel Count Depth is non-negative.

QE_RX_ETOP_PARITY
(5)
The pointer to the top of the Rx empty stack has even parity. This is an
error if the driver has initialized all of the pointers to be odd. If 64K cell
buffers are used, or if the driver did not initialize the pointers to have
odd parity by using the MSB as a parity bit, this bit may be set.
The pointer to the top of the Rx empty stack has odd parity.

QE_TX_ETOP_PARITY
(4)
The pointer to the top of the Tx empty stack has even parity. This is an
error if the driver has initialized all of the pointers to be odd. If 64K cell
buffers are used, or if the driver did not initialize the pointers to have
odd parity by using the MSB as a parity bit, this bit may be set.
The pointer to the top of the Tx empty stack has odd parity.

QE_UNMAPPED_VI
(3)
The Rx UTOPIA I/F is delivering a cell from a virtual input that it was
not supposed to be polling.
0
.The Rx UTOPIA I/F is not delivering a cell from a VI that it was not
supposed to be polling.
QE_VO_MISMATCH
(2)
1
0
The Tx UTOPIA I/F is asking for a cell from a VO which does not have
a cell. This is normal if TX_OC_12C_MODE = 1.
The Tx UTOPIA I/F is not asking for a cell from a VO which does not
have a cell.
QE_RX_CIRC_LINK
(1)
1
A circular link is being written to the RX linked list. This non-recover-
able state occurs when a link is added to the RX linked list that points to
itself. The device should be reset and reinitialized.
0
1
A circular link is not being written to the Rx linked list.
QE_TX_CIRC_LINK
(0)
A circular link is being written to the Tx linked list. This non-recover-
able state occurs when a link is added to the TX linked list that points to
itself. The device should be reset and reinitialized.
0
A circular link is not being written to the Tx linked list.
