7. Calculates the external bus clock speed of the MPU.
8. Delays for 750 milliseconds.
9. Determines the CPU base board type.
10. Sizes the local read/write memory (i.e., DRAM).
11. Initializes the read/write memory controller. Sets base address of
memory to $00000000.
12. Retrieves the speed of read/write memory.
13. Initializes the read/write memory controller with the speed of
read/write memory.
14. Retrieves the speed of read only memory (i.e., Flash).
15. Initializes the read only memory controller with the speed of read
only memory.
16. Enables the MPU's instruction cache.
17. Copies the MPU's exception vector table from $FFF00000 to
$00000000.
18. Verifies MPU type.
19. Enables the superscalar feature of the MPU (superscalar processor
boards only).
20. Verifies the external bus clock speed of the MPU.
21. Determines the debugger's console/host ports, and initializes the
PC16550A.
22. Displays the debugger's copyright message.
23. Displays any hardware initialization errors that may have occurred.
24. Checksums the debugger object, and displays a warning message if
the checksum failed to verify.
25. Displays the amount of local read/write memory found.
26. Verifies the configuration data that is resident in NVRAM, and
displays a warning message if the verification failed.
