Due to hardware errata in Aero controllers, reads to certain fusion registers could intermittently return all zeroes. This behavior is transient in nature and subsequent reads will return valid value. Fix: For Aero controllers, any read will retry the read operations from certain registers for maximum three times, if read returns zero.
