The reserved encodings are set to 0 indicating an uninitialized state.
25:28 EU breakpoints euBreakpoint: These bits indicate that a breakpoint has occurred in one of the four
execution units. Each execution unit has one bit dedicated to it. A 1 in any of these bits
indicates that the associated execution unit has issued breakpoint. These bits are sticky
and must be overwritten to continue. These bits are cleared to zero at reset. See Table
13-35 for the bit encoding.

29 E Enable External Breakpoint.
0 Do not enable external breakpoint to cause a halt condition
1 Allow external breakpoint to cause a halt condition
30 I Enable Internal Breakpoint
0 Do not enable internal breakpoint to cause a halt condition
1 Allow internal breakpoint to cause a halt condition
31 EB Enable Breakpoint (this bit must be always set to allow any kind of breakpoint to halt the
task)
0 Disable breakpoint
1 Enable breakpoint
