A write to TDR clears the CSR trigger status bits, CSR[BSTAT].
Section Table 5-14., “TDR Field Descriptions,” describes how to handle multiple
breakpoint conditions.

Level-x trigger. This is a Rev. B function. The Level-x Trigger bit determines the logic operation for the
trigger between the PC_condition and the (Address_range & Data_condition) where the inclusion of a
Data condition is optional. The ColdFire debug architecture supports the creation of single or double-level
triggers.
TDR[15]
0 Level-2 trigger = PC_condition & Address_range & Data_condition
1 Level-2 trigger = PC_condition | (Address_range & Data_condition)
TDR[14]
0 Level-1 trigger = PC_condition & Address_range & Data_condition
1 Level-1 trigger = PC_condition | (Address_range & Data_condition)
Enable breakpoint. Global enable for the breakpoint trigger. Setting TDR[EBL] enables a breakpoint
trigger. Clearing it disables all breakpoints.

The debug module has no hardware interlocks, so to prevent
spurious breakpoint triggers while the breakpoint registers are
being loaded, disable TDR (by clearing TDR[29,13] before
defining triggers.
