Interrupt Status Register (0x384)
There are two ways to acknowledge interrupts:
1) Acknowledge selected Interrupts by writing a ‘1’ to the appropriate interrupt status bit. This method is
used when the IRQ_ACK_CONF bit in the Global Configuration Register is set to ‘0’ (default).
2) Acknowledge all interrupts by reading the interrupt status register. This method is used when the
IRQ_ACK_CONF bit in the Global Configuration Register is set to ‘1’.
For an interrupt status bit to be set, the interrupt must be enabled prior to the interrupt event.
An interrupt is asserted if at least one bit is set in the Interrupt Status Register.
