When a machine-check exception occurs, the processor does one of the following:
Which action is taken depends on the value of the MSR[ME] bit, whether or not debug mode was enabled
at reset, and (if debug mode is enabled) the values of the CHSTPE (checkstop enable) and MCIE (machine
check enable) bits in the debug enable register (DER).
processor is in the checkstop state, instruction processing is suspended and cannot be restarted without
resetting the core.
An indication is sent to the USIU which may generate an automatic reset in this condition. Refer to
