Reset, Stop Mode Recovery, and Low
Voltage Detection
Reset Types
PS022825-0908
The Reset Controller within the Z8 Encore! XP
Mode Recovery operation and provides indication of low supply voltage conditions. In
typical operation, the following events cause a Reset:
When the device is in STOP mode, a Stop Mode Recovery is initiated by either of the
The low voltage detection circuitry on the device (available on the 8-pin product versions
only) performs the following functions:
The Z8 Encore! XP F082A Series provides several different types of Reset operation. Stop
Mode Recovery is considered as a form of Reset.
operating characteristics. The System Reset is longer if the external crystal oscillator is
enabled by the Flash option bits, allowing additional time for oscillator start-up.

Power-On Reset (POR)
Voltage Brownout (VBO)
Watchdog Timer time-out (when configured by the WDT_RES Flash Option Bit
to initiate a reset)
External RESET pin assertion (when the alternate RESET function is enabled by
the GPIO register)
On-chip debugger initiated Reset (OCDCTL[0] set to 1)
Watchdog Timer time-out
GPIO Port input pin transition on an enabled Stop Mode Recovery source
Generates the VBO reset when the supply voltage drops below a minimum safe
level.
Generates an interrupt when the supply voltage drops below a user-defined level
(8-pin devices only).
