XE8806A/XE8807A
Another reset source is the bit Sleep in the RegSysReset register. This source is fully controlled by software and is
only used during the sleep mode.
Four internal reset signals are generated from these sources and distributed through the system:
nresetcold:
is asserted on POR or by the NRESET pin
nresetglobal: is asserted when nresetcold or any other enabled reset source is active
nresetsleep:
is asserted when the circuit is in sleep mode
nresetpconf:
is asserted when nresetglobal is active and if the EnResetPConf bit in the RegSysCtrl
register is set. This reset is generally used in the different ports. It allows to maintain the port configuration
unchanged while the rest of the circuit is reset.
Table 6-5 shows a summary of the dependency of the internal reset signals on the various reset sources.
In all the tables describing the different registers, the reset source is indicated.

Reset source description
6.5.1
Power On Reset
The power on reset (POR) monitors the external supply voltage. It activates a reset on a rising edge of this supply
voltage. The reset is inactivated only if the internal voltage regulator has started up. The POR block performs no
precise voltage level detection.
6.5.2
NRESET pin
Applying a low input state on the NRESET pin can activate the reset.
6.5.3
Programmable Port A input combination
Port A (if present in the product) can generate a reset signal.
See the description of the Port A for further
information.
6.5.4
Watchdog reset
The Watchdog will generate a reset if the EnResetWD bit in the RegSysCtrl register has been set and if the
watchdog is not cleared in time by the processor. See chapter 6.8 describing the watchdog for further information.
