47 // Purpose: Support code to extend the generic monitor code to support
48 // MIPS(R) processors.
49 // Description: Further board specific support is in other files.
50 // This file contains:
51 // register names lookup table
54 // Interval timer - This should really belong to the application
57 // Should not contain:
58 // low level uart getchar and putchar functions
59 // delay function to support uart
