INT_EN—Interrupt Enable Register
This register contains the interrupt masks for IRQ. Writing 1 to any of the bits enables the
corresponding interrupt as a source for IRQ. Bits in the 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.
