Interrupt Enable Register (0x90 – 0x91): IER (Continued)
Bit
Default Value
R/W
Description
2
0x0
RW
EDIE Energy Detect Interrupt Enable
When this bit is set, the wake-up from energy detect interrupt is enabled.
When this bit is reset, the energy detect interrupt is disabled.
1
0x0
RO
Reserved.
0
0x0
RW
DEDIE Delay Energy Detect Interrupt Enable
When this bit is set, the delay energy detect interrupt is enabled.
When this bit is reset, the delay energy detect interrupt is disabled.
Note: the delay energy detect interrupt till device is ready for host access.
Interrupt Status Register (0x92 – 0x93): ISR
This register contains the status bits for all QMU and other interrupt sources.
When the corresponding enable bit is set, it causes the interrupt pin to be asserted.
This register is usually read by the host CPU and device drivers during interrupt service routine or polling. The register
bits are not cleared when read. The user has to write “1” to clear.
Bit
Default Value
R/W
Description
15
0x0
RO

LCIS Link Change Interrupt Status
When this bit is set, it indicates that the link status has changed from link up to link down,
or link down to link up.
This edge-triggered interrupt status is cleared by writing 1 to this bit.
14
0x0
RO
(W1C)
TXIS Transmit Interrupt Status
When this bit is set, it indicates that the TXQ MAC has transmitted at least a frame on the
MAC interface and the QMU TXQ is ready for new frames from the host.
This edge-triggered interrupt status is cleared by writing 1 to this bit.
13
0x0
RO
(W1C)
RXIS Receive Interrupt Status
When this bit is set, it indicates that the QMU RXQ has received at least a frame from the
MAC interface and the frame is ready for the host CPU to process.
This edge-triggered interrupt status is cleared by writing 1 to this bit.
12
0x0
RO
Reserved
11
0x0
RO
(W1C)
RXOIS Receive Overrun Interrupt Status
When this bit is set, it indicates that the Receive Overrun status has occurred.
This edge-triggered interrupt status is cleared by writing 1 to this bit.
10
0x0
RO
Reserved
9
0x1
RO
(W1C)
TXPSIS Transmit Process Stopped Interrupt Status
When this bit is set, it indicates that the Transmit Process has stopped.
This edge-triggered interrupt status is cleared by writing 1 to this bit.
8
0x1
RO
(W1C)
RXPSIS Receive Process Stopped Interrupt Status
When this bit is set, it indicates that the Receive Process has stopped.
This edge-triggered interrupt status is cleared by writing 1 to this bit.
7
0x0
RO
Reserved
6
0x0
RO
(W1C)
TXSAIS Transmit Space Available Interrupt Status
When this bit is set, it indicates that Transmit memory space available status has occurred.
When this bit is reset, the Transmit memory space available interrupt is disabled.
