Chapter 6 Background Debug Module (BDMV4) Block Description
6.1.2
BDM is available in all operating modes but must be enabled before firmware commands are executed.
Some system peripherals may have a control bit which allows suspending the peripheral function during
background debug mode.
6.1.2.1
All of these operations refer to the part in run mode. The BDM does not provide controls to conserve power
during run mode.
6.1.2.2
If the part is in secure mode, the operation of the BDM is reduced to a small subset of its regular run mode
operation. Secure operation prevents access to FLASH or EEPROM other than allowing erasure.

Nine hardware commands using free cycles, if available, for minimal CPU intervention
Hardware commands not requiring active BDM
15 firmware commands execute from the standard BDM firmware lookup table
Instruction tagging capability
Software control of BDM operation during wait mode
Software selectable clocks
When secured, hardware commands are allowed to access the register space in special single-chip
mode, if the FLASH and EEPROM erase tests fail.
Normal operation
General operation of the BDM is available and operates the same in all normal modes.
Special single-chip mode
In special single-chip mode, background operation is enabled and active out of reset. This allows
programming a system with blank memory.
Special peripheral mode
BDM is enabled and active immediately out of reset. BDM can be disabled by clearing the
BDMACT bit in the BDM status (BDMSTS) register. The BDM serial system should not be used
in special peripheral mode.
Emulation modes
General operation of the BDM is available and operates the same as in normal modes.
Modes of Operation
Regular Run Modes
Secure Mode Operation
The BDM serial system should not be used in special peripheral mode since
the CPU, which in other modes interfaces with the BDM to relinquish
control of the bus during a free cycle or a steal operation, is not operating in
this mode.
