Operation
Option Bit Configuration by Reset
Programmable Flash option bits allow user configuration of certain aspects of Z8 Encore!
F0830 Series operation. The feature configuration data is stored in the Flash program
memory and read during reset. The features available for control through the Flash option
bits are:
•
•
•
•
•
•
•
This section describes the type and configuration of the programmable Flash option bits.
Each time the Flash option bits are programmed or erased, the device must be reset for the
change to be effective. During any Reset operation (system reset or Stop Mode Recovery),
the Flash option bits are automatically read from Flash program memory and written to the
Option Configuration registers, which control Z8 Encore! F0830 Series device operation.
Option bit control is established before the device exits reset and the eZ8 CPU begins code
execution. The Option Configuration registers are not part of the register file and are not
accessible for read or write access.
Watchdog Timer time-out response selection–interrupt or system reset
Watchdog Timer enabled at reset
The ability to prevent unwanted read access to user code in program memory
The ability to prevent accidental programming and erasure of all or a portion of the user
code in program memory
Voltage Brown-Out configuration always enabled or disabled during STOP Mode to re-
duce STOP Mode power consumption
OSCILLATOR Mode selection for high, medium and low power crystal oscillators or
external RC oscillator
