Data breakpoint invert. Provides a way to invert the logical sense of all the data breakpoint
comparators. This can develop a trigger based on the occurrence of a data value other than the
DBR1 contents.
Enable address bits. Setting an EAx bit enables the corresponding address breakpoint. If all three
bits are cleared, this breakpoint is disabled.

Enable address breakpoint inverted. Breakpoint is based outside the range between
ABLR1 and ABHR1.
Enable address breakpoint range. Breakpoint is based on the range defined between
ABLR1 and ABHR1.
Enable address breakpoint low. The breakpoint is based on the address in ABLR1.
