FUNCTIONAL DEVICE OPERATIONS
LOGIC COMMANDS AND REGISTERS
MOD2, MOD1 - Mode Control Bits
These write-only bits select the operating mode and allow to
clear the watchdog in accordance with Table 41 , Mode
Control Bits.
Table 41. Mode Control Bits
Any access to the MCR or Voltage Status Register (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 inputs.
Writing the Wake-up Control Register (WUCR) will return the
Wake-up Status Register (WUSR).

Voltage Status Register - VSR
Returns the status of the several voltage monitors. This
register is also returned when writing to the Mode Control
Register (MCR).

LxWE - Wake-up Input x Enable
Read VSOV VSUV VDDOT BATFAIL
VSOV - V SUP Over-voltage
This read-only bit indicates an over-voltage condition on the
VS1 pin.
1 = Over-voltage condition.
0 = Normal condition.
VSUV - V SUP Under-voltage
This read-only bit indicates an under-voltage condition on the
VS1 pin.
1 = Under-voltage condition.
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-up Input x enabled.
0 = Wake-up 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 WUCR.

0 = Normal condition.

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 33911 had a Power On Reset (POR).
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 WUSR.
1 = Lx Wake-up.
0 = Lx Wake-up disabled or selected as analog input.
