B.17.2 RANGEOUT signal
ARM DDI 0029G
The address comparator output of the watchpoint is used to drive the write enable for
the CHAINOUT latch. The input to the latch is the output of the data comparator from
the same watchpoint. The output of the latch drives the CHAIN input of the breakpoint
comparator. The address YYY is stored in the breakpoint register and when the CHAIN
input is asserted, the breakpoint address matches and the breakpoint triggers correctly.
The RANGEOUT signal is derived as follows:
The RANGEOUT output of watchpoint register 1 provides the RANGE input to
watchpoint register 0. This RANGE input enables you to couple two breakpoints
together to form range breakpoints.
Selectable ranges are restricted to being powers of 2. For example, if a breakpoint is to
occur when the address is in the first 256 bytes of memory, but not in the first 32 bytes,
program the watchpoint as follows:
For Watchpoint 1:
1.
2.
3.
For Watchpoint 0:
1.
2.
3.
4.
If Watchpoint 0 matches but Watchpoint 1 does not, that is the RANGE input to
Watchpoint 0 is 0, the breakpoint is triggered.
Program Watchpoint 1 with an address value of
of
Clear the ENABLE bit.
Program all other Watchpoint 1 registers as normal for a breakpoint. An address
within the first 32 bytes causes the RANGE output to go HIGH but does not
trigger the breakpoint.
Program Watchpoint 0 with an address value of
of
Set the ENABLE bit.
Program the RANGE bit to match a 0.
Program all other Watchpoint 0 as normal for a breakpoint.
