FUNCTIONAL DEVICE OPERATIONS
LOGIC COMMANDS AND REGISTERS
This read-only bit indicates an over-voltage condition on
1 = Over-voltage condition.
0 = Normal condition.
This read-only bit indicates an under-voltage condition on
1 = Under-voltage condition.
0 = Normal condition.
This read-only bit indicates that the main voltage regulator
1 = Over-temperature Prewarning
0 = Normal
This read-only bit is set during power-up and indicates that
Any access to the MCR or VSR will clear the BATFAIL flag.
1 = POR Reset has occurred
0 = POR Reset has not occurred
This register is used to control the digital wake-up input.

L1WE - Wake-up Input Enable
and Sleep mode the L1WE bit activates the L1 input for wake-
up. If the L1 input is selected on the analog multiplexer, the
L1WE is masked to 0.
Wake-up Status Register - WUSR
and is also returned when writing to the WUCR.
L1 - Wake-up input 1
L1 input is not enabled, then the Wake-up status will return 0.
allows to verify the L1 input has caused the wake-up, by first
reading the Interrupt Status Register (ISR) and then reading
the WUSR. The source of the wake-up is only reported on the
first WUCR or WUSR access.
This write-only bit enables/disables the L1 input. In Stop
1 = Wake-up Input enabled.
0 = Wake-up Input disabled.
This register is used to monitor the digital wake-up input
This read-only bit indicates the status of the L1 input. If the
After a wake-up from Stop or Sleep mode this bit also
1 = L1 pin high, or L1 is the source of the wake-up.
0 = L1 pin low, disabled or selected as an analog input.
