5.8.3
This high page register contains a single write-only control bit. A serial background command such as
WRITE_BYTE must be used to write to SBDFR. Attempts to write this register from a user program are
ignored. Reads always return 0x00.

BDFR is writable only through serial background debug commands, not from user programs.

System Background Debug Force Reset Register (SBDFR)
Loss of Clock — Reset was caused by a loss of external clock.
0 Reset not caused by loss of external clock
1 Reset caused by loss of external clock
Low-Voltage Detect — If the LVDRE bit is set and the supply drops below the LVD trip voltage, an LVD reset will
occur. This bit is also set by POR.
0 Reset not caused by LVD trip or POR.
1 Reset caused by LVD trip or POR.
Background Debug Force Reset — A serial background command such as WRITE_BYTE can be used to allow
an external debug host to force a target system reset. Writing 1 to this bit forces an MCU reset. This bit cannot
be written from a user program.
