Register 7: Reset Cause (RESC), offset 0x05C
This field specifies the cause of the reset event to software. The reset value is determined by the
cause of the reset. When an external reset is the cause (EXT is set), all other reset bits are cleared.
However, if the reset is due to any other cause, the remaining bits are sticky, allowing software to
see all causes.

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
LDO Reset
When set, indicates the LDO circuit has lost regulation and has
generated a reset event.
Software Reset
When set, indicates a software reset is the cause of the reset event.
Watchdog Timer Reset
When set, indicates a watchdog reset is the cause of the reset event.
Brown-Out Reset
When set, indicates a brown-out reset is the cause of the reset event.
Power-On Reset
When set, indicates a power-on reset is the cause of the reset event.
External Reset
When set, indicates an external reset (RST assertion) is the cause of
the reset event.
