FUNCTIONAL DEVICE OPERATIONS
LOGIC COMMANDS AND REGISTERS
WDOFF - Watchdog Off
This read-only bit signals that the watchdog pin connected to
Ground and therefore disabled. In this case watchdog
timeouts are disabled and the device automatically enters
Normal mode out of Reset. This might be necessary for
software debugging and for programming the Flash memory.
Configuration Register - CFR
This register controls the cyclic sense timing multiplier.
Table 28. Configuration Register - $D
C3 C2 C1 C0
1 = Watchdog is disabled
0 = Watchdog is enabled
WDWO - Watchdog Window Open
This read-only bit signals when the watchdog window is open
for clears. The purpose of this bit is for testing. Should be
ignored in case WDERR is High.

Analog Multiplexer Control Register - MUXCR
This register controls the analog multiplexer and selects the
divider ration for the Lx input divider.

CYSX8 - Cyclic Sense Timing x 8.
This write-only bit influences the cyclic sense and Forced
1 = Multiplier enabled
0 = None
Interrupt Mask Register - IMR
This register allows masking of some of the interrupt sources.
No interrupt will be generated to the MCU and no flag will be
set in the ISR register. The 5.0V Regulator over-temperature
prewarning interrupt and Under-voltage (VSUV) interrupts
can not be masked and will always cause an interrupt.
Writing to the IMR will return the ISR.

These write-only bits selects which analog input is
When disabled or when in Stop or Sleep mode, the output
buffer is not powered and the ADOUT0 output is left floating
to achieve lower current consumption.

the high side block.
