ARMF — Arm Flag
CNT3:CNT2:CNT1:CNT0 — FIFO Valid Count
Freescale Semiconductor
While DBGEN = 1, this status bit is a read-only image of the ARM bit in DBGC. This bit is set by
writing 1 to the ARM control bit in DBGC (while DBGEN = 1) and is automatically cleared at the end
of a debug run. A debug run is completed when the FIFO is full (begin trace) or when a trigger event
is detected (end trace). A debug run can also be ended manually by writing 0 to the ARM or DBGEN
bits in DBGC.
These bits are cleared at the start of a debug run and indicate the number of words of valid data in the
FIFO at the end of a debug run. The value in CNT does not decrement as data is read out of the FIFO.
The external debug host is responsible for keeping track of the count as information is read out of the
FIFO.
1 = Debugger armed.
0 = Debugger not armed.
