15.1.2.3
The BDM can be used until all bus masters (e.g., CPU or XGATE) are in stop mode. When CPU is in a
low power mode (wait or stop mode) all BDM firmware commands as well as the hardware
BACKGROUND command can not be used respectively are ignored. In this case the CPU can not enter
BDM active mode, and only hardware read and write commands are available. Also the CPU can not enter
a low power mode during BDM active mode.
If all bus masters are in stop mode, the BDM clocks are stopped as well. When BDM clocks are disabled
and one of the bus masters exits from stop mode the BDM clocks will restart and BDM will have a soft
reset (clearing the instruction register, any command in progress and disable the ACK function). The BDM
is now ready to receive a new command.
