WDERR - Watchdog Error
watchdog resistor. In this condition the watchdog is using the
internal, lower precision timebase. The Windowing function is
disabled.
WDOFF - Watchdog Off
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.
WDWO - Watchdog Window Open
open for clears. The purpose of this bit is for testing. Should
be ignored in case WDERR is High.
Analog Multiplexer Control Register - MUXCR
the divider ration for the Lx input divider.
LXDS - Lx Analog Input Divider Select
analog inputs. Voltage is internally clamped to VDD.

This read-only bit signals the detection of a missing
1 = WDCONF pin resistor missing
0 = WDCONF pin resistor not floating
This read-only bit signals that the watchdog pin connected
1 = Watchdog is disabled
0 = Watchdog is enabled
This read-only bit signals when the watchdog window is
1 = Watchdog window open
0 = Watchdog window closed
This register controls the analog multiplexer and selects
This write-only bit selects the resistor divider for the Lx
0 = Lx Analog divider: 1
1 = Lx Analog divider: 3.6 (typ.)
