Chapter 3. Using the Monitor/Debug Firmware 3-41

System Call Functions

C example:

int

board_isr_remove (void *handler)

{

asm( "addi r10,r0,0x0041");

asm( "sc");

}

3.5.6 EXIT_TO_dBUG

This function transfers the control back to the dBUG, by terminating the user code. The register

context is preserved.

C example (see “scif.s”file : anything in R10 besides 0x0000, 0x0001, 0x0020, 0x0030, 0x0031,

0x0040, 0x0041):

asm( "addi r10,r0,0x0063");

asm( "sc");
