Halt status. Returns cause of last CPU halt
0 CPU was halted by HALT debug command
1 CPU was halted by software or hardware breakpoint
Debug locked. Returns value of DBGLOCK bit
0 Debug interface is not locked
1 Debug interface is locked
Oscillators stable. This bit represents the status of the
CLKCON.XSOC_STB and CLKCON.HFRC_STB register bits.
0 Oscillators not stable
1 Oscillators stable
Stack overflow. This bit indicates when the CPU writes to
DATA memory space at address 0xFF which is possibly a
stack overflow
0 No stack overflow
1 Stack overflow

12.9.7 Hardware Breakpoints
The debug command SET_HW_BRKPNT
is used to set a hardware breakpoint. The
CC2510Fx/CC2511Fx supports up to four
hardware breakpoints. When a hardware
breakpoint is enabled, it will compare the
CPU address bus with the breakpoint..
When a match occurs, the CPU is halted.
When issuing the SET_HW_BRKPNT, the
external host must supply three data bytes
that define the hardware breakpoint. The
hardware breakpoint itself consists of 18
bits while three bits are used for control
purposes. The format of the three data
bytes for the SET_HW_BRKPNT
command is as follows.
The first data byte consists of the
following:
• bits 7-5 : unused
• bits 4-3 : breakpoint number; 0-3
• bit 2
: 1=enable, 0=disable
• bits 1-0 : Memory bank bits. Bits
17-16 of hardware breakpoint.
The second data byte consists of bits 15-8
of the hardware breakpoint.
The third data byte consists of bits 7-0 of
the hardware breakpoint.
