Description
0:4
MASK
RW
R
X
This value determines the maximum size of the trace
buffer in SRAM. It specifies the
most-significant bit of the POSITION.POINTER field
that can be updated by automatic
increment. If the trace tries to advance past this power
of two, the POSITION.WRAP bit is set to 1, the
POSITION.POINTER[MASK:0] bits are set to zero,
and the POSITION.POINTER[AWIDTH-4:MASK+1]
bits remain unchanged.
This field causes the trace packet information to be
stored in a circular buffer of size 2(MASK+4) bytes,
that can be positioned in memory at multiples of this
size.
Valid values of this field are zero to AWIDTH-4. Values
greater than the maximum have the same effect as the
maximum.
5
TSTARTEN
RW
R
0
Trace start input enable. If this bit is 1 and the
TSTART signal is HIGH, then the EN bit is
set to 1. Tracing continues until a stop condition
occurs.
6
TSTOPEN
RW
R
0
Trace stop input enable. If this bit is 1 and the TSTOP
signal is HIGH, then the EN bit is set to 0. If a trace
packet is being written to memory, the write is
completed before tracing is stopped.
7
SFRWPRIV
RW
R
1
Special Function Register Write Privilege bit. If this bit
is 0, then User or Privileged AHB-Lite read and write
accesses to the Special Function Registers are
permitted. If this bit is 1, then only Privileged write
accesses are permitted and User write accesses are
ignored. The HPROT[1] signal determines if an access
is User or Privileged.
Note
- SFR read accesses are not controlled by this bit and
are always permitted.
- This bit is implemented only if User/Privilege support
is present in the MTB configuration. If User/Privilege
support is absent, then the behavior of this bit is
RAZ/WI and the value of the HPROT[1] signal is
ignored.
8
RAMPRIV
RW
R
0
SRAM Privilege bit. If this bit is 0, then User or
Privileged AHB-Lite read and write accesses to the
SRAM are permitted. If this bit is 1, then only
Privileged AHB-Lite read and write accesses to the
SRAM are permitted and User accesses are RAZ/WI.
The HPROT[1] signal determines if an access is User
or Privileged.
Note
This bit is implemented only if User/Privilege support is
present in the MTB configuration. If User/Privilege
support is absent, then the behavior of this bit is
RAZ/WI and the value of the HPROT[1] signal is
ignored.
9
HALTREQ
RW
RW
0
Halt request bit. This bit is connected to the halt
request signal of the trace logic, EDBGRQ.
When HALTREQ is set to 1, EDBGRQ is asserted if
DBGEN is also HIGH.
The HALTREQ bit can be automatically set to 1 using
the FLOW.WATERMARK field.
