STATUS 2 REGISTER

Address: 0x4000142C, Reset: 0xC000, Name: SR2
SR2 is a status register that further complements the status information provided by SR0 and SR1.
SR2 contains sticky interrupt sources optionally enabled via the CR1 register. These interrupt sources alert the CPU when the WUT count has
changed, when the prescaled gated clock that controls the advancement of the WUT count has activated, when a trim boundary has occurred,
when the 32-bit WUT count has rolled over, and when the modulo 60 version of the WUT count has rolled over.
All interrupt sources in SR2 are sticky, active high level signals. Each one can individually be cleared by writing a value of 0b1 to its bit position
in SR2.
