• EIR: Event Identification Register (Read Only) (Address = 2h)

The EIR (Event Identification Register) indicates factors of various interrupts on the MSM9405.

Each of eight bits corresponds to each interrupt bit assignment set on the ENR. The EIR works

as the status register even if the interrupt is disabled. When an event occurs, each corresponding

bit is set to "1". When the system is reset, all bits are reset to "0".
