Description
BWE - Breakpoint / Watchpoint Enable
00 = Disabled
01 = Breakpoint enabled
10 = Reserved
11 = Watchpoint enabled
Reserved
AME - Address Mask Enable
This bit is only present in BWCxA registers.
0 = Disabled.
1 = Enabled. BWAxB will be used to bitwise mask
the PC compare according to this function:
BP A: (PC & BWA_B) == (BWA_A & BWA_B)
BP B: Will never trigger
Reserved
EOC - EVTO Control
0 = Breakpoint/watchpoint status indication is not
output on EVTO
1 = Breakpoint/watchpoint status indication is
output on EVTO
Reserved
Description
Address of data for breakpoint or watchpoint
generation.
