14 Vector module error
Machine checks are taken regardless of the current IPL. If the machine
check exception vector bits (<1:0>) are not both one, the operation of the
processor is undefined. The exception is taken on the interrupt stack and
the IPL is raised to 1F (hex). See Table 4–9 for the complete list of machine
check codes.
