Table 36-5. CSR Field Descriptions
Field
Description
31–28
BSTAT
Breakpoint Status. Provides read-only status (from the BDM port only) information concerning hardware
breakpoints. BSTAT is cleared by a TDR write or by a CSR read when a level-2 breakpoint is triggered or a level-1
breakpoint is triggered and the level-2 breakpoint is disabled.
0000 No breakpoints enabled
0001 Waiting for level-1 breakpoint
0010 Level-1 breakpoint triggered
0101 Waiting for level-2 breakpoint
0110 Level-2 breakpoint triggered
27
FOF
Fault-on-fault. If FOF is set, a catastrophic halt occurred and forced entry into BDM. FOF is cleared when CSR is
read (from the BDM port only).
26
TRG
Hardware breakpoint trigger. If TRG is set, a hardware breakpoint halted the processor core and forced entry into
BDM. Reset, the debug
GO
command or reading CSR (from the BDM port only) clear TRG.
25
HALT
Processor halt. If HALT is set, the processor executed a HALT and forced entry into BDM. Reset, the debug
GO
command, or reading CSR (from the BDM port only) clear HALT.
24
BKPT
Breakpoint assert. If BKPT is set, BKPT was asserted, forcing the processor into BDM. Reset, the debug
GO
command, or reading CSR (from the BDM port only) clear BKPT.
23–20
HRL
Hardware revision level. Indicates, from the BDM port only, the level of debug module functionality. An emulator
could use this information to identify the level of functionality supported.
0000 Revision A
0001 Revision B
0010 Revision C
0011 Revision D
1001 Revision B+ (This is the value used for this device)
1011 Revision D+
19
DBT
Debug translate. Indicates, from the BDM port only, the presence of the debug translate block that compresses
the PST/DDATA stream to 1/2 the core clock.
0 Debug translate block is not present
1 Debug translate block is present
18
BKD
Breakpoint disable. Disables the normal BKPT input signal functionality, and allows the assertion of this pin to
generate a debug interrupt.
0 Normal operation
1 BKPT is edge-sensitive: a high-to-low edge on BKPT signals a debug interrupt to the ColdFire core. The
processor makes this interrupt request pending until the next sample point occurs, when the exception is
initiated. In the ColdFire architecture, the interrupt sample point occurs once per instruction. There is no
support for nesting debug interrupts.
17
PCD
PSTCLK disable.
0 PSTCLK is fully operational
1 Disables the generation of the PSTCLK and PSTDDATA output signals, and forces these signals to remain
quiescent
Note: When PCD is set, do not execute a wddata instruction or perform any debug captures. Doing so, hangs the
device.
16
IPW
Inhibit processor writes. Setting IPW inhibits processor-initiated writes to the debug module’s programming model
registers. Only commands from the external development system can modify IPW.
