C.13.1 Breakpoint and watchpoint coupling example
ARM DDI 0165B
Coupling breakpoints and watchpoints
You can couple watchpoint units 1 and 0 together using the CHAIN and RANGE
inputs. Using CHAIN enables Watchpoint 0 to be triggered only if Watchpoint 1 has
previously matched. Using RANGE enables you to perform simple range checking by
combining the outputs of both watchpoints.
Let:
Av[31:0]
Am[31:0]
A[31:0]
Dv[31:0]
Dm[31:0]
D[31:0]
Cv[8:0]
Cm[7:0]
C[9:0]
CHAINOUT signal
The CHAINOUT signal is derived as follows:
WHEN (({Av[31:0],Cv[4,2:0]} XNOR {A[31:0],C[4,2:0]}) OR
{Am[31:0],Cm[4:0]} == 0xFFFFFFFFF)
CHAINOUT = ((({Dv[31:0],Cv[6:4]} XNOR {D[31:0],C[7:5]}) OR
{Dm[31:0],Cm[7:5]}) == 0x7FFFFFFFF)
The CHAINOUT output of Watchpoint register 1 provides the CHAIN input to
Watchpoint 0. This CHAIN input allows for quite complicated configurations of
breakpoints and watchpoints.
There is no CHAIN input to Watchpoint 1 and no CHAIN output from Watchpoint 0.
