11.10.3.15 Breakpoint / Watchpoint Address Mask (BWAM1, BWAM2)

The Breakpoint / Watchpoint Address Mask Registers allow the user to mask ARM bus addresses for

internal watchpoint units 1 and 2 on a bit-wise granularity.

11.10.3.16 Breakpoint / Watchpoint Data (BWD1, BWD2)

The Breakpoint / Watchpoint Data Registers are compared with ARM bus values for internal watchpoint

units 1 and 2.

11.10.3.17 Breakpoint / Watchpoint Data Mask (BWDM1, BWDM2)

The Breakpoint / Watchpoint Data Mask Registers allow the user to mask ARM bus data values on a

byte-wise granularity for internal watchpoint units 1 and 2.
