Software Interrupt Enable (SW_INT_EN)
On a transition from low to high, this register bit triggers the software
interrupt.
RESERVED
Master Bus Error Interrupt Enable (MBERR_INT_EN)
When set high, the Master Bus Error is enabled to generate an interrupt.
Slave Bus Error Interrupt Enable (SBERR_INT_EN)
When set high, the Slave Bus Error is enabled to generate an interrupt.
RESERVED
GPIO [2:0] (GPIOx_INT_EN)
When set high the GPIOx are enabled as interrupt sources.
GP Timer Interrupt Enable (GPT_INT_EN)
When set high the General Purpose Timer is enabled as an interrupt
source.
PHY Interrupt Enable (PHY_INT_EN)
When set high, the PHY interrupt is enabled as an interrupt source.
Wake Event Interrupt Enable (WAKE_INT_EN)
When set high, wake event detection is enabled as an interrupt source.
RESERVED
Interrupt Control Register (INT_CTL)
Interrupts are enabled/disabled through this register. Refer to
page 28
Note: The DMAC interrupt (DMAC_INT) is enabled through the DCSR.
