8.4.4.3 IRT Status Register

The IRT status register (IRTSTAT) is a 32-bit read/write register available for IRT firmware status and is only reset on a cold Reset (POR or BOR). The IRTSTAT register usage is defined by the IRT firmware. It can be used to store secure boot and other status information across the device Resets. The IRTSTAT register is read-only except when the PLCK bit = ‘0’.
