Reset and Stop Mode Recovery
PS025113-1212
Reset Types
The reset controller in the Z8 Encore! F0830 Series controls RESET and Stop Mode
Recovery operations. In a typical operation, the following events can cause a reset:
•
•
•
•
•
When the device is in STOP Mode, a Stop Mode Recovery event is initiated by either of
the following occurrences:
•
•
The VBO circuitry on the device generates a VBO reset when the supply voltage drops
below a minimum safe level.
The Z8 Encore! F0830 Series provides different types of Reset operations. Stop Mode
Recovery is considered a form of reset. Table 9 lists the types of resets and their operating
characteristics. The duration of a system reset is longer if the external crystal oscillator is
enabled by the Flash option bits; the result is additional time for oscillator startup.
Power-On Reset (POR)
Voltage Brown-Out (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)
A Watchdog Timer time-out
A GPIO port input pin transition on an enabled Stop Mode Recovery source
