(1) Check to determine if switching to the virtual mode is possible
(a) The items in Table 9.1 are checked to determine if switching to the virtual
mode is possible.
When all check items of Table 9.1 are normal, switching to the virtual mode is
executed.
(b) If an error of at least one item of Table 9.1, the real mode/virtual mode
switching error detection flag (M2045) turns on, and the error code is stored
in the real mode/virtual mode switching error information storage register
(SD504 to SD506).
Refer to APPENDIX 1.7 for the error codes which are stored in the SD504 to
SD506.
Check item
(Note-1): It is not check target for the operating system software version "00H or later".
