INH/LIMP:
ILEN = 1
ILC = 1
HIGH
When pin INH/LIMP is used as inhibit output, a pull-down resistor to GND ensures a
default LOW level. The pin can be set to HIGH according to the state diagram.
When pin INH/LIMP is used as limp-home output, a pull-up resistor to V
default HIGH level. The pin is automatically set to LOW when the SBC enters Fail-safe
mode.
The WAKE input comparator is triggered by negative edges on pin WAKE. Pin WAKE has
an internal pull-up resistor to BAT42. It can be operated in two sampling modes which are
selected via the WAKE Sample Control bit (WSC):
If V3 is continuously ON, the WAKE input will be sampled continuously, regardless of the
level of bit WSC.
The dedicated bits Edge Wake-up Status (EWS) and WAKE Level Status (WLS) in the
System Status register reflect the actual status of pin WAKE. The WAKE port can be
disabled by clearing the WEN bit in the System Configuration register.

Sampling synchronized to the cyclic behavior of V3 if the bit is cleared; see
This is to save bias current within the external switches in low-power operation. Two
repetition times are possible, 16 ms and 32 ms.
