FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
Table 11. Mode Control Bits
Voltage Status Register - VSR
Returns the status of the several voltage monitors. This
register is also returned when writing to the Mode Control
register MRC.
VSOV - VSUP Over-voltage
This read-only bit indicates an over-voltage condition on
the VS1 pin.
1 = Over-voltage condition.
0 = Normal condition.
VSUV - VSUP Under-voltage
This read-only bit indicates an under-voltage condition on
the VS1 pin.
1 = Under-voltage condition.
0 = Normal condition.
VDDOT - Main Voltage Regulator Over-temperature
Warning
This read-only bit indicates that the main voltage regulator
temperature reached the Over-temperature Prewarning
Threshold.
1 = Over-temperature Prewarning
0 = Normal
BATFAIL - Battery fail flag.
This read-only bit is set during power-up and indicates that
the analog die had a Power On Reset (POR).
Any access to the Mode Control Register (MCR) or
Voltage Status Register (VSR) will clear the BATFAIL flag.
1 = POR Reset has occurred
0 = POR Reset has not occurred
Wake-up Control Register - WUCR
This register is used to control the digital Wake-up inputs.
Writing the Wake-up Control Register WUCR will return the
Wake-up Status Register WUSR.
Table 13. Wake-up Control Register - $2
LxWE - Wake-up Input x Enable
This write-only bit enables/disables which Lx inputs are
enabled. In Stop and Sleep mode the LxWE bit determines
which wake inputs are active for wake-up. If one of the Lx
inputs is selected on the analog multiplexer, the
corresponding LxWE is masked to 0.
1 = Wake-Input x enabled.
0 = Wake-Input x disabled.
Wake-up Status Register - WUSR
This register is used to monitor the digital wake-up inputs
and is also returned when writing to the Wake-up Control
Register WUCR.
Lx - Wake-up input x
This read-only bit indicates the status of the corresponding
Lx input. If the Lx input is not enabled then the according
Wake-up status will return 0.
After a wake-up form Stop or Sleep mode these bits also
allow to determine which input has caused the wake-up, by
first reading the Interrupt Status Register ISR and then
reading the Wake-up Status Register WUSR.
1 = Lx Wake-up.
0 = Lx Wake-up disabled or selected as analog input.
LIN Control Register - LINCR
This register controls the LIN physical interface block.
Writing the LIN Control Register returns the LIN Status
