Interrupt Enable Register (INT_EN)

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.
