The AMD-K6-2E processor does not support the generation of a
machine-check exception. However, the processor does provide
a 64-bit machine-check address register (MCAR), a 64-bit
machine-check type register (MCTR), and a machine check
enable (MCE) bit in CR4.
Because the processor does not support machine check
exceptions, the contents of the MCAR and MCTR registers are
only affected by the WRMSR instruction and by RESET being
sampled asserted (where all bits in each register are reset to 0).
The formats for the machine-check address register and the
machine-check type register are shown in Figure 30 and Figure
31, respectively.
