Description: This data table represents EJTAG Instruction Break configuration. It specifies an Instruction Break for the specified channel and address (with optional mask). Hardware may place restrictions on the values (e.g. bit 0 of the address is likely forced to 0, and bit 0 of the mask is forced to 1).

The default mask is 0xffffffff (all address bits relevant). Be careful when specifying a mask, since many values (like 0, 1, etc) can cause an immediate break to occur.

The instruction break behaves according to this pseudo-code:

if ((ProgramCounter & Mask) == (Address & Mask)) Generate debug exception;
