5.8.3
This 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)
Internal Clock Generation Module Reset — Reset was caused by an ICG module reset.
0 Reset not caused by ICG module.
1 Reset caused by ICG module.
Low Voltage Detect — If the LVD reset is enabled (LVDE = LVDRE = 1) and the supply drops below the LVD trip
voltage, an LVD reset occurs. The LVD function is disabled when the MCU enters stop. To maintain LVD operation
in stop, the LVDSE bit must be set.
0 Reset not caused by LVD trip or POR.
1 Reset caused by LVD trip or POR.
Background Debug Force Reset — A serial background mode command such as WRITE_BYTE allows 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.
