13.1.1.3 Interrupt Enable Register (INT_EN)
Three Port 10/100 Managed Ethernet Switch with MII
Datasheet
Offset:
05Ch
Size:
32 bits
This register contains the interrupt enables for the IRQ output pin. Writing 1 to any of the bits enables
the corresponding interrupt as a source for IRQ. Bits in the Interrupt Status Register (INT_STS) register
will still reflect the status of the interrupt source regardless of whether the source is enabled as an
interrupt in this register (with the exception of SW_INT_EN). For descriptions of each interrupt, refer
to the Interrupt Status Register (INT_STS) bits, which mimic the layout of this register.
