Table 11-17 describes the bit assignments of DWT Function Registers 0-3.
Function
Reserved.
This bit is set when the comparator matches, and indicates that the operation defined by
FUNCTION has occurred since this bit was last read. This bit is cleared on read.
Reserved.
Identity of a second linked address comparator for data value matching when
DATAVMATCH == 1 and LNK1ENA == 1.
Identity of a linked address comparator for data value matching when DATAVMATCH ==
1.
