Software Interrupt (SW_INT)
This interrupt is generated when the SW_INT_EN bit of the
Register (INT_EN)
Device Ready (READY)
This interrupt indicates that the LAN9313/LAN9313i is ready to be
accessed after a power-up or reset condition.
1588 Interrupt Event (1588_EVNT)
This bit indicates an interrupt event from the IEEE 1588 module. This bit
should be used in conjunction with the
Register (1588_INT_STS_EN)
event within the 1588 module.
Switch Fabric Interrupt Event (SWITCH_INT)
This bit indicates an interrupt event from the Switch Fabric. This bit should
be used in conjunction with the
(SW_IPR)
Fabric.
Port 2 PHY Interrupt Event (PHY_INT2)
This bit indicates an interrupt event from the Port 2 PHY. The source of the
interrupt can be determined by polling the
Flags Register
Port 1 PHY Interrupt Event (PHY_INT1)
This bit indicates an interrupt event from the Port 1 PHY. The source of the
interrupt can be determined by polling the
Flags Register
RESERVED
GP Timer (GPT_INT)
This interrupt is issued when the
(GPT_CNT)
RESERVED
GPIO Interrupt Event (GPIO)
This bit indicates an interrupt event from the General Purpose I/O. The
source of the interrupt can be determined by polling the
I/O Interrupt Status and Enable Register (GPIO_INT_STS_EN)
RESERVED
Interrupt Status Register (INT_STS)
This register contains the current status of the generated interrupts. A value of 1 indicates the
corresponding interrupt conditions have been met, while a value of 0 indicates the interrupt conditions
have not been met. The bits of this register reflect the status of the interrupt source regardless of
whether the source has been enabled as an interrupt in the
indicated as R/WC, writing a 1 to the corresponding bits acknowledges and clears the interrupt.
