Note: 1) The Vbat_sl defines the minimum slope required on VBAT. Correct start-up of the circuit is not guaranteed
if this slope is too slow. In such a case, a delay has to be built using the RESET pin.
Note: 2) The minimal watchdog timeout period is guaranteed when the internal oscillators are used. The watchdog
takes its clock from the low prescaler. In case an external clock source is used, the RC oscillator must be enabled
also (EnRC=1 in RegSysClock). Otherwise, the watchdog is stopped (see the clock block documentation).
Note: 3) For the circuit versions XE8801 and XE8805. Gives the time the reset is active after the falling edge of the
RESET pin.
Note: 4) For the circuit versions XE8801A and XE8805A. Gives the time the reset is active after the falling edge of
the RESET pin.
