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
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)
