OCD Status Register
DBGHALT DBGBRK
BRKHALT bit is set. 
0 = The device is running.
1 = The device is in Debug Halt mode.
BRKHALT—Breakpoint halt
This bit determines what action the OCD takes when a Breakpoint occurs. If this bit is set
to one, then the DBGHALT bit is automatically set to one when a breakpoint occurs. If
BRKHALT is zero, then the CPU will loop on the breakpoint.
0 = CPU loops on current instruction when breakpoint occurs.
1 = A Breakpoint sets DBGHALT to one.
BRKEN—Enable breakpoints
This bit controls the behavior of the
default, these generate an illegal instruction system trap. If this bit is set to one, these
events generate a Breakpoint instead of a system trap. The resulting action depends upon
the BRKHALT bit. 
0 =
1 =
DBGSTOP—Debug Stop mode
This bit controls the system clock behavior in STOP mode. When set to one, the system
clock will continue to operate in STOP mode.
0 = Stop mode debug disabled. system clock stops in STOP mode.
1 = Stop mode debug enabled. system clock runs in STOP mode.
Reserved
This bit is reserved and must be written to zero.
STEP—Single step an instruction
This bit is used to single step an instruction when in Debug Halt Mode. This bit is auto-
matically cleared after an instruction is executed.
0 = Idle
1 = Single Step an Instruction.
